You can put this solution on YOUR website! Write the equation of the line passing through each of the given pairs of points. Write your result in slope-intercept form,where possible
(-1,3) =(X1,Y1)and (4,-2)=(X2,Y2)
(2,-3) and (2,4)
EQN.IS.
(Y-Y1)=(X-X1)(Y2-Y1)/(X2-X1)
Y-3=(X+1)(-2-3)/(4+1)=-X-1
Y=-X+2
---------------------
Y+3=(X-2)(4+3)/(2-2).......HERE SINCE D.R IS ZERO WE USE
(Y-Y1)(X2-X1)=(X-X1)(Y2-Y1)..WE GET
(Y-Y1)(2-2)=(X-2)(4+3)
7(X-2)=0
X-2=0
