Question

Select the equation of the line that goes through the point (6,-10) and is

parallel to the equation below.
6x + 2y = 12

Answer 1

3x+y = 8

yes, its parallel

Explanation:

Choices:

a. 3x+y=18

b. 3x+y=-8

c. 3x+y=8

d. 3x+y=-10

1. if we plug in (6, -10) to 3x+y=8 we get:

3(6) + (-10) = 8

18 - 10 = 8

8 = 8, this is true

2. if we simplify 6x+2y=12 we get:

2y = -6x + 12

y = -3x + 6

if we simplify 3x+y = 8 we get

y = -3x + 8

the slopes of the equations are the same, therefore they are parallel.
