Question 888217: find the slope of the line satisfying the given conditions: through (-9,-6) and (-5,8)
Answer by jim_thompson5910(35256)   (Show Source):
You can put this solution on YOUR website! Two generic points that define a straight line are (x1, y1) and (x2, y2)
In this case, (x1, y1) = (-9, -6), which means x1=-9 and y1=-6
and (x2, y2) = (-5, 8), which means x2=-5 and y2=8
So x1=-9, y1=-6, x2=-5, and y2=8.
-------------------
Now use the slope formula
m = (y2-y1)/(x2-x1)
m = (8-(-6))/(-5-(-9))
m = (8+6)/(-5+9)
m = 14/4
m = 7/2
So the slope of the line that passes through the two points is 7/2
