Answer:
5/2
Step-by-step explanation:
As we go from point L(0, 5) to point Q(4, -5), x increases by 4 and y decreases by 10. Thus, the slope of this line is m = rise / run = 10/4, or m = 5/2. This 5/2 is also the slope of any line parallel to this one.
B
Using 2 points (x1,y1) (x2,y2): Slope is defined as (y2-y1)/(x2-x1)
So in this case (-5-5)/(4-0) = -10/4 which simplifies to -5/2 or B
d
Given
f(x) = 5x , then substitute x = - 1, that is
f(- 1) = 5 × - 1 = - 5 → d
145
180-137=43
43+102=145
