Answer:
(- 1, 1 )
Step-by-step explanation:
Given the 2 equations
y = 3x + 4 → (1)
y = x + 2 → (2)
Substitute y = 3x + 4 into (2)
3x + 4 = x + 2 ( subtract x from both sides )
2x + 4 = 2 ( subtract 4 from both sides )
2x = - 2 ( divide both sides by 2 )
x = - 1
Substitute x = - 1 into either of the 2 equations and evaluate for y
Substituting x = - 1 into (2)
y = - 1 + 2 = 1
Solution is (- 1, 1 )

Answer:
number 11 is slope=3, then number 12 is slope=-2, then number 13 is slope=4 and number 14 is slope =1. i got my answers by looking at the x axis. In a y=mx+b whatevers infront of the x is your slope. idk what 15 is though its weird lol Good luck! :)
