Answer:
(-15, 13)
Step-by-step explanation:
-3(8x + 9y = -3)
4( 6x + 7y = 1)
-24x - 27y = 9
24x + 28y = 4 (add both equations)
y = 13
6x + 7*13= 1
6x + 91= 1
6x = 1 -91
x = -91/6
x = -15
F(5) is like X is 5
you just do this
f(5)=-2x+1
=-2(5)+1
=-10+1
= -9

The slope can be calculated with the following formula:

In this case, you have the following points:
