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 2 (� − 5) d. � = 1 2 (� + 5)

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?

The volume is 2212m cubed

Y=-2x-6 is the answer
