Question 1124499: Find the value of p so that the line through (p,4) and (3, -1) has a slope of -5/8. Found 2 solutions by rothauserc, MathLover1:Answer by rothauserc(4718) (Show Source): You can put this solution on YOUR website! slope = (y2 - y1)/(x2 - x1)
:
-5/8 = (-1 -4)/(3-p)
:
-5/8 = -5/(3-p)
:
cross multiply the fractions
:
-5(3-p) = -40
:
3-p = 8
:
*************
p = 3-8 = -5
*************
:
check the answer
:
(-1-4)/(3-(-5)) = -5/8
:
answer checks

given:
point (,)=(,)
point (,)=(,)
use formula or slope:
....plug in given values
.......solve or ...simplify
so, (,)=(,)
check the slope:
(,) and (, ) and see if it has a slope of
