A. The slope can be found by m=%28y1-y2%29%2F%28x1-x2%29
Given the points (5,-2) and (-1,-9), m=%28-2-%28-9%29%29%2F%285-%28-1%29%29
m=7%2F6
B. Given the equation 4x-5y=10 put it into slope intercept form - y=mx%2Bb
-5y=-4x%2B10
y=%284%2F5%29x-2
The equation fits the form y=mx%2Bb; the slope is m.
m=4%2F5
