Question

State the slope and y-intercept of the graph of 9-x=2y

please explain how you got your answer. Thank you.

Answer 1

slope: -1/2

y-int: 9/2

Explanation:

rearrange 9-x=2y into slope-intercept form: y=mx+b (m being slope and b is y-intercept)

2y = -x + 9

divide both sides by 2 to isolate the y and get:

y = -x/2 + 9/2

m (slope) = -(1)/2

b (y-int) = 9/2
