Khan Academy Slope from graph !! Please help me I am having so much trouble !!!! PLEASEEE HELPPPPPPPP
Answer:
The slope of this line is 5/3. Or, 1 2/3. The equation would be y = 5/3x
Step-by-step explanation:
You are in luck my friend!
To find the slope of a line on a graph, you need to find the rise over run. You need to pick two definite points on a graph. An intersection whereyou can clearly tell the value. For example 1,1 and -4,-4. Then use your finger and trace how many units up you have to go, and then how many units across. (This is a very common topic so if you need further help just look up rise over run. This fact will put you ahead, do you see how the line intersects between the 2 and the 3 in the y axis? This is called the y intersect, you will see it added to the slope so if the equation is y = 5/3x it would be written as y = 5/3x + 2.5 because that is where the line intersects with the y axis.) Back to slope, remember that the formula is always rise/run. Later, you will find to points and use a slope formula. y2-y1/x2-x1.
Hope this helped :)

Answer:
A. Incorrect
B. Incorrect
C. Correct
D. Incorrect
Step-by-step explanation:
y = 5x + 6 means that Player A had 6 points and got 5 points per question.
The equation for the linear function is y = 2x + 6 because Player B had 6 points and gains 2 points per question.
A is incorrect because Player B gains 2 points and Player A gains 5 points
B. is incorrect because both of them have 6 points
C. is correct because Player A gains 5 points while Player B gains 2 points
D. is incorrect because there is already a correct answer and the evidence we needed was not given

2x - 8x + 1 = 49
this seriously makes no sense
Answer:
x = -8
Step-by-step explanation:
2x - 8x + 1 = 49
⇒ 2x - 8x = 49 - 1
⇒ -6x = 48
⇒ x = [tex]\frac{48}{-6}[/tex]
= -8
Answer:
X = -8
Step-by-step explanation:
Add similar elements: 2x-8=6x
-6x+1=49
Subtract 1 from both sides:
-6x+1 -1 =49 - 1
Simplify:
-6x=48
Divide both sides by -6
-6x /-6= 48 /6
Which then gets you the answer up top!

To make orange fizz, Noah mixes 4 scoops of powder with 6 cups of water. Andre mixes 5 scoops of powder with cups of water. Create a double number line or a table that shows different amounts of powder and water that taste the same as Noah’s mixture.
Answer:
Noah mixes 4 scoops of powder with 6 cups of water.
Means Noah ratio will be or 0.67
Andre mixes 5 scoops of powder with 8 cups of water
Means Andre ratio will be or 0.62
As, or 0.66 > 0.62
We can say that content of orange powder will be more in Noah mixture than in Andre's Mixture.
Hence, Noah's mixture will taste more like orange, than Andre's mixture.

An artist builds a sculpture out of metal and wood that weighs 14.9 kilograms.
¾ of this weight is metal, and the rest is wood.
How much does the wood part of the sculpture weigh?
Answer:
Given is a sculpture that is built up of metal and wood, and the weight of this sculpture is 14.9 kilograms.
It says that three-fourth of the total weight is metal and says to find the weight of wooden part.
We can find the weight of metal part and then subtract it from the total weight to calculate the answer.
Step-by-step explanation:
Total weight = 14.9 kilograms.
Metal part = three-fourth of total weight =
Wooden part = 14.9 - 11.175 = 3.725 kilograms.
Hence, the wooden part is 3.725 kilograms.
Write the equation of the line in the graph in POINT-SLOPE form.
Answer: y= -8/4x+2
Step-by-step explanation:
find our y-intercept and slope
(rise over run to find your slope)
the two points it provides are what you will use to find the slope
see how for you run from point A to B then your rise as well
it should be rise=-8 run=4
0,2 is your y-intercept
now use your equation y= mx+b
b=your y-intercept and mx= your slope
plug the numbers in and you will get the answer
-15/-18=10/x
what is X?
Answer:
12
Step-by-step explanation:
(-15)/(-18) = 10/x cross multiply expressions
-15x = -180 since both sides are negative we can write without the sign
15x = 180 divide both sides by 15
x = 12
Choose the expression that is equal to 28.3.
33 + 27.2 – 6.8 + 24 – 3.1
33 + 27.2 – (6.8 + 24 – 3.1)
[33 + (27.2 – 6.8)] + 24 – 3.1
33 + 27.2 – (6.8 + 24) – 3.1
this is 6th grade work. show how you got it bc i need to show my work
Answer:none of them
Step-by-step explanation:
None of them equal 28.3. The closest is number 3, which is 26.3. Do the parenthesis, then the brackets, then add and subtract
