Answer 2

K, thanks!

Answer 3

What is it you are trying to solve

Answer 4

This is a linear equation

Answer 5

Given above equation I have to I dentify Y intercept, x intercept and slope...do I get these directly from the equation w/o attempting to solve antything?

Answer 6

I understand

Answer 7

To find the y-intercept you must make x=0
so
Y = 5000 + 7.5X becomes Y = 5000 + 7.5(0)
Therefore y = 5000

Answer 8

To find the x intercept you make y=0
Therefore 0 = 5000 + 7.5X
Subtract 5000 from both sides
-5000 = 7.5x
Divide both sides by 7.5
x = -666.66666.......

Answer 9

Question: making x= 0...is that a rule or random b/c you know this stuff?

Answer 10

Well if you want to find where the equation crosses the y-axis (y-intercept) x HAS to be zero. Because if x is any other number, say 2. You wouldn't be on the axis you would be in one of the quadrants. Same with finding the x-intercept.
