Question

The equation of a line is 5x + 2y = 9. What is the slope of this line?

-2/5
-5/2
9/2
9/5

Answer 1

Slope is -5/2

Get y by itself.

Answer 2

-5/2

Explanation:

y=mx+b

m represents slope

b represents the vertical shift, or y-intercept

9= 2y + 5x <-- isolate for y

y=(-5x+9)/2

y=(-5/2)x+(9/2)

Following the formula above, m = -5/2
