====================================
1)point-slope form;
Y-Y1=m(X-X1)
y-5=%28-1%2F3%29%28x-%28-2%29%29
y-5=%28-1%2F3%29x-2%2F3
y=%28-1%2F3%29x%2B13%2F3
2)a)3x-4y-12=0
Put in slope-intercept form;
-4y=-3x+12
y=%283%2F4%29x-3
slope(gradient)=3%2F4
y-intercept=-3
b)4x+5y=10
5y=-4x+10
y=%28-4%2F5%29x%2B2
gradient+=+-4%2F5
y-intercept=2
