5x-2y=8
-2y = 8 -5x
-y = (8-5x):2
y = -4 + 2.5x
f(x) = 2.5x -4

The slope-intercept form:
y=mx+b
Subtract 5x from both sides:
-2y=-5x+8
Divide -2 from both sides:
y=5/2x-4

5x-2y=8 -5x from both sides. -2y=8-5x
divide both sides by -2
y = -4 + 2.5x

5x-2y = 8
5x = 8 + 2y
x = (8+2y)/5

(5x-8)/2 = y

5x-2y=8
-2y=8-5x
2y=5x-8
y=(5x-8)/2
y=f(x)=(5x-8)/(2)
