Slope intercept form y = -8x - 81
Point slope form (y - 7) = -8 (x + 11)
Wherever you see an x, replace it with -2,
So f(-2) = 2(-2^2) -15
= (2x4)-15
= -7
Answer:
C
Step-by-step explanation:
y=mx+b, where x any are variables, m is the slope and b is the y-int.
Step 1: Find the y-int
y-int = 3.25 (13/4)
Step 2: Find the slope using RISE/RUN
-13/7
Answer is C
Hope that helps
Answer:
y=x+4
Step-by-step explanation:
2y=2x+4 simplifies down to y=x-2. Since the two lines are parallel, they have to have the same slope, but different y-intercepts. This means that we just have to find the y-intercept that will allow our line to pass through (-5, -1).
If we input the coordinates into what of our equation we have thus far (y=x+b), we just have to find what b needs to equal to make the equation true.
-1=-5+b -1=-5+4
b = 4 -1=-1
