Answer:
y = 2x - 6
Step-by-step explanation:
14-6/10-6 = 8/4 = 2 = slope
6 = 2(6) + b
6 = 12 + b
b = -6

Step-by-step explanation:
write an equation of the line that passes through (0 0) and (2 6)
Answer:
y = 3x
Step-by-step explanation:
Slope equation:
y2 - y1
--------
x2 - x1
----------------------------------------------------------------------------------------------------------------
6 - 0 6
m = ----------- = ----- = 3
2 - 0 2
Your slope is 3.
----------------------------------------------------------------------------------------------------------------
Equation:
y = mx + b
Plug in the slope and you get:
y = 3x + b
----------------------------------------------------------------------------------------------------------------
Now to find b, you can use either coordinate point. So I will show you both ways :)
(0,0) (2,6)
0 = 3(0) + b 6 = 3(2) + b
Multiply 0 and 3 Multiply 2 and 3
0 = 0 + b 6 = 6 + b
Subtract 0 to 0 Subtract 6 from 6
0 = b 0 = b
There is no y-intercept
----------------------------------------------------------------------------------------------------------------
Your answer: y = 3x
Hope this helped :)
Marcello is investigating plant growth. The flowers he planted in his garden were expected to grow two inches in one year. This year there was more rainfall, so the flowers grew three inches. What percentage more did the flowers grow than was expected?
25%
50%
75%
100%
Answer:
50%
Step-by-step explanation:
it was predicted to grow 2 inches and that would be 100% each inch is 50% it grew one inch more than predicted so it grew 50% more
1/2 = 1/a + b/c make b the subject
Answer:
b = [tex]\frac{ac-2c}{2a}[/tex]
Step-by-step explanation:
Given
[tex]\frac{1}{2}[/tex] = [tex]\frac{1}{a}[/tex] + [tex]\frac{b}{c}[/tex]
Multiply through by 2ac to clear the fractions
ac = 2c + 2ab ( subtract 2c from both sides )
ac- 2c = 2ab ( divide both sides by 2a )
[tex]\frac{ac-2c}{2a}[/tex] = b

Answer:
Angle 1,Angle 4
Step-by-step explanation:
They're
The value of angle ∠1 and angle ∠4 will be congruent with angle ∠8. The correct options are D.
What are lines and angles?Lines are straight with little depth or width. Perpendicular lines, intersecting lines, transversal lines, and other types of lines will be covered. An angle is a shape formed by two rays emerging from a common point. In this field, you may also come across alternate and corresponding angles.
Given that there are two lines e and f cut by the transversal line g making different angles.
From the property of the alternate interior angles the two angles, 1 and 4 are congruent to angle 8. The value is mathematically written as,
∠1 = ∠4 = ∠8
Therefore, the value of angle ∠1 and angle ∠4 will be congruent with angle ∠8. The correct options are D.

Starting at 6:00 a.m., Lin spent a day hiking through a canyon. This graph shows her elevation (in meters) at some different times. Negative values of x represent times earlier than noon, and positive values of x represent times later than noon.
Please help me with this
Answer:
First, we know that the 0 in the horizontal axis corresponds to the noon.
Then:
a) Lin's elevation at noon in meters.
We need to see the elevation when x = 0.
This is the point that is just on top of the y-axis, we can see that when x = 0, we have y = 6.
Then at noon, her altitude was 6 meters.
b) At 8:00 am, her elevation was 2m
Remember that the x-component represents time, and x = 0 represents the noon.
8:00 am is 4 hours before noon, then 8:00am is represented with x = -4
and at this time her elevation is 2m, then y = 2.
This means that the point that represents this is (-4, 2)
c) At 4:00 pm Lin was at sea level (her elevation was 0m)
Same reasoning than before: x = 0 is the noon, then 4:00 pm is four hours after this, then 4:00 pm is represented with x = 4.
And here her altitude is 0m, then y = 0.
This point is written as (4, 0)
d) Here we can see that at 6:00 am her elevation was negative, and at 4:00pm her elevation is 0.
And we know that:
0 > negative numbers.
Then her altitude increased in this interval of time.
Answer:
Its 0
