Answer:

y = -3x + 4

Step-by-step explanation: Substitute the numbers in for x & y to see which one is the answer.

(-1, 7):

y = -3x + 4

7 = -3(-1) + 4

7 = 3 + 4

7 = 7

TRUE


(2, -2):

y = -3x + 4

-2 = -3(2) + 4

-2 = -6 + 4

-2 = -2

TRUE


(7, -17):

y = -3x + 4

-17 = -3(7) + 4

-17 = -21 + 4

-17 = -17

TRUE


(10, -26):

y = -3x + 4

-26 = -3(10) + 4

-26 = -30 + 4

-26 = -26

TRUE


Hope this helps you!!! :)

f(-4)=3(-4)-7
= -12 - 7
= -19
