How do you find the slope of a line through (1,3) and (-2,5)
The slope formula is: highlight%28m=%28y2-y1%29%2F%28x2-x1%29%29, m=slope and (x1,y1) and (x2,y2) are given points.
(x1,y1)=(1,3) and (x2,y2)=(-2,5)
m=%285-3%29%2F%28-2-1%29
m=2%2F-3

Also, how do you find the slope of a parallel line passing (1,5) and (-1,0)
Parallel lines have equal slopes, so use the slope formula to find the slope between these two points and it will be the same as the line parallel to this one.
(x1,y1)=(1,5) and (x2,y2)=(-1,0)
m=%280-5%29%2F%28-1-1%29
m=-5%2F-2
m=5%2F2

Happy Calculating!!!
