Answer:

(-2, 3)

Explanation:

Substitute 2x + 7 for y in y = -2x - 1


  • 2x + 7=-2x-1

Add 2x to both sides


  • 2x + 7 + 2x = -2x - 1 + 2x

  • 4x + 7 = -1

Subtract 7 from both sides.


  • 4x + 7 - 7 = -1 - 7

  • 4x = -8

Divide both sides by 4.


  • (4x)/(4)= (-8)/(4)

  • x = -2

Substitute -2 for x in y = 2x + 7


  • y = 2(-2)+7

Simplify both sides.


  • y = -4 + 7

  • y = 3

Therefore, the answer is (-2, 3).
