Question

39. The equation of a line in standard form is

4x – 2y = 20. Which of the following is the
equation of the same line in slope-intercept
form?
A. y = 2x – 10
B. y = -2x + 10
C. y = 2x – 5
D. y = –2x – 5

Answer 1

Let's solve for x.

4x−2y=20

Step 1: Add 2y to both sides.

4x−2y+2y=20+2y

4x=2y+20

Step 2: Divide both sides by 4.

4x/4

= 2y+20/4

x= 1/2y+5

Answer: x= 1/2y+5
