Question

Which point is a solution to the system of equations?
y = 3x +4
y =x+2

Answer 1

X = -1, y = 1

( -1 , 1 )

Explanation:

You can set them equal to each other since they both equal y

3x + 4 = x + 2

subtract x from both sides to get all the x’s on one sides

2x + 4 = 2

subtract 4 from both sides

2x = -2

divide by 2

x = -1

plug -1 into either equation to get y

-1 + 2 = 1
