Answer:
f(x) = -2x + 11
Step-by-step explanation:
okay so if f(-2) = 15 and f(1) = 9
i used desmos to picture it and i got f(x) = -2x + 11
because f(-2) = -2(-2) + 11 = 4 + 11 = 15 so f(-2) = 15
and f(1) = -2(1) + 11 = -2 + 11 = 9 so f(1) = 9
Can someone help me out with this please

Step-by-step explanation:
slope =
The second y point is 16 and the first is -4, so:
(16) - (-4)
Which can be written as 16 + 4 because a double negative makes a positive. Do the same for the x points, -7 and -3:
(-7) - (-3)
(-7) + (3)
Now solve both of them:
16 + 4 = 20
(-7) + 3 = -4
Remember, the slope formula is y over x, so we still need to put it into the fraction form:
You can reduce this to , or 5.
