You can use the formula y1-y2=m(x1-x2)
to find m, you just do (y2-y1)/(x2-x1) so....
(115-80)/(80-40)= 35/40= 7/8
then plug it into the point slope equation:
y-115=7/8(x-80)
y-115=7/8x-70
y= 7/8 x + 45
Answer:
A
Step-by-step explanation:
As 2 < a < 5, only option A suffices this condition, because 2 < 3 < 5.
Answer:

Step-by-step explanation:
I think the second Q on the base is R.
Then the side LM corresponds to the side PQ and the side LN corresponds to the side PR. Therefore we have the proportion:
