First find the slope by the formula $\"m=%28y2-y1%29%2F%28x2-x1%29\"$ which leads to $\"m=%283-1%29%2F%282-%28-1%29%29\"$ then $\"m=2%2F3\"$ which then we can use the equation $\"y-y1=m%28x-x1%29\"$ which then leads to $\"y-1=%282%2F3%29%28x-%28-1%29%29\"$ which leads to $\"y-1=%282%2F3%29x%2B2%2F3\"$ which then becomes $\"y=%282%2F3%29x%2B2%2F3%2B1\"$ which finally becomes $\"y=%282%2F3%29x%2B5%2F3\"$ \n" ); document.write( "
