Question

Help With Both Please!

Answer 1

1. (0,2)

2. (-2,-1)

Explanation:

1.

y = 2x + 2

y = x + 2

2x + 2 = x + 2

2x = x

x = 0

Now we put 0 back in for x and solve for y

y = 2(0) + 2

y = 2

So, our answer for Q1 is (0,2)

2.

y = 3x + 5

y = -x - 3

3x + 5 = -x - 3

4x + 5 = -3

4x = -8

x = -2

Now we put -2 back in for x and solve for y

y = 3(-2) + 5

y = -6 + 5

y = -1

So, our answer for Q2 is (-2,-1)
