Which equation has an � −intercept of (5,0) and a � −intercept of (0, −2.5)?

a. � + 2.5 = 5(� − 0)
b. � − 2.5 = 5(� − 0)

c. � = 1

So much clearer! Thank you (seriously).

Use the point-slope form of the eq'n of a str. line. Find the slope first:
0-(-2.5) 2.5
m = ------------- = -------- = 1/2
5 - 0 5

Then, y-0 = (1/2)(x-5)

Which answer choice do you believe matches this?
