+m=+%28y2-y1%29%2F%28x2-x1%29+
+%28%28-6%29-%28-4%29%29%2F%28%28-8%29-%28-1%29%29+
= +%28-6%2B4%29%2F%28-8%2B1%29+
= +2%2F7+
Lets find the value of the intercept.
y=mx+b
-6=2/7(-8)+ b
-6+16/7=b
b=-42+16/7
b=-26/7
Now, take the slope (2/7) and intercept -26/7 to get the equation
y = mx + b
y= 2/7x - 26/7
