Since both is equal to p(a), you can set them as equal to each other:
15 = 2a - 3
18 = 2a
9 = a
Answer:
R(16,-8)
Step-by-step explanation:
if (x1,y1) and (x2,y2) are coordinates of two points and (x,y) the coordinate of midpoint.
then x=(x1+x2)/2
and y=(y1+y2)/2
let coordinates of R are (x,y)
4=(-8+x)/2
8=-8+x
x=8+8=16
-3=(2+y)/2
-6=2+y
y=-6-2=-8
so R is (16,-8)

Step-by-step explanation:
The answers are:
• A
• C
• E
Formula for slope is y2 - y1 over x2 - x1
Just from looking at the first set of points I know that the slope is 0 or undefined because the line is vertical. There is no y intercept.
For the second one I know that it is a horizontal line meaning that there is no slope either. It does have a y intercept though.pointslopeform y = 4. Standardform y = 4
