Which line has an y-intercept of -2

Mathematics
1 answer:
DiKsa [7]3 years ago
7 0
The y-intercept is found when x is set to 0.

Set x to equal 0 for both equations:

3(0) - 2y = -6
-2y = -6

Divide both sides by -2:

y = 3

The y-intercept of this equation is 3, so the first line does not have the y-intercept of -2.

-
0 + 2y = -2
2y = -2

Divide both sides by 2:

y = -1

The y-intercept of this equation is -1, so the second line does not have the y-intercept of -2.

Neither line has a y-intercept of -2.
