I pretty sure the answer to the first question is 3,000. I got this by adding the 272 more Carter got to the 764 and then adding the 764 that Jack collected. I then got 1,800. I divided it by 3 cause it was 3/5 of the final project. I got 600 from that. The I did 600 times 5 and got 3,000. I don't know if it's right but it might help...

What is the equation of the line in slope -intercept form? *
A. y= x +8
B. y= x - 8
C. y = 8x +8
D. y = 8x - 8

Answers

Answer:

Step-by-step explanation:

The equation of the line in slope -intercept form is y=x-8, Option b is correct.

What is Slope of Line?

The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.

The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.

The slope of line passing through two points (x₁, y₁) and (x₂, y₂) is

m=y₂-y₁/x₂-x₁

From the graph let us take two points of line joining which are (8, 0) and (0, -8).

m=-8-0/0-8=1

So slope of line is 1.

Now let us find find the y intercept

0=1(8)+b

0-8=b

b=-8

Slope intercept form of line is y=x-8

Hence, the equation of the line in slope -intercept form is y=x-8, Option b is correct.
