Question

Write the equation for 5x + 2y = 3 in slope-intercept form.

A. y = 5/2x -3/5
B. y = -5/2x +3/2
C. y = -2/5x + 3/5

Answer 1

B. y = -5/2x +3/2

Explanation:

5x + 2y = 3

We want to get this in the form

y = mx +b where m is the slope and b is the y intercept

Subtract 5x from each side

5x -5x+ 2y =-5x+ 3

2y = -5x+3

Divide by 2

2y/2 = -5x/2 +3/2

y = -5/2 x +3/2
