What is the y-coordinate of the point of intersection for the two lines given below? a: 4 b: -14 c: -3 d: -2

B. -14

Step-by-step explanation:

If you solve the system using the method of elimination, the y terms will automatically cancel each other out without any manipulation at all.  So go with it and solve for x first.  If the y terms cancel out, you're left with x = -3.

If x = -3, sub that value in for x in eitheer one of the original equations and solve for y:

becomes

and

so
