A(-5, 4) B(3, -3) and C(5, -2)


A(-5, 4) B(3, -3)...find equation of the line passing through
m=%28y%5B2%5D-y%5B1%5D%29%2F%28x%5B2%5D-x%5B1%5D%29=%28-3-4%29%2F%283-%28-5%29%29=-7%2F8
y-y%5B1%5D=m%28x-x%5B1%5D%29
y-4=%28-7%2F8%29%28x-%28-5%29%29
y-4=-%287%2F8%29%28x%2B5%29
y=-%287%2F8%29x-%287%2F8%295%2B4
y=-%287%2F8%29x-35%2F8%2B32%2F8
y=-%287%2F8%29x-3%2F8


B(3, -3) and C(5, -2)
...find equation of the line passing through

y-y%5B1%5D=m%28x-x%5B1%5D%29
y-%28-3%29=%281%2F2%29%28x-3%29
y%2B3=%281%2F2%29%28x-3%29
y=%281%2F2%29x-3%2F2-3
y=%281%2F2%29x-9%2F2

A(-5, 4) and C(5, -2)
...find equation of the line passing through

y-y%5B1%5D=m%28x-x%5B1%5D%29
y-4=-%283%2F5%29%28x-%28-5%29%29
y=-%283%2F5%29%28x%2B5%29%2B4
y=-%283%2F5%29x-%283%2F5%295%2B4
y=-%283%2F5%29x-3%2B4
y=-%283%2F5%29x%2B1
