Question

What is the slope and the y
-intercept of the equation 9+27/2x=−3/2y
. Write the y
-intercept as an ordered pair.(1 point)
The slope is
. The y
-intercept is (
).

Answer 1

First put the equation in y = mx + b form:

9 + (27/2)x = −(3/2)y
Multiply both sides by −2/3:
y = −(2/3)(9 + (27/2)x) = −9x − 6

So the slope is −9. The y-intercept is (0, −6).
