Show your work.
A. y = 5/4x + 2.5
B. y = 1.2x - 5/2
C. y = - 5/4 - 5/2
D. y = - 5/4x + 5/2

The general equation of the slope intercept form is y = mx + b. The first step is to subtract the whole equation by 5x. This leaves 4y on the left side. Then, divide the whole equation by 4, which results to option D. y = - 5/4x + 5/2

5x + 4y = 10
- 5x - 5x
4y = - 5x + 10
y = - 1¹/₄x + 2¹/₂
The answer is D.
