consider the linear equation 2x-3y=-3. if (-3,y1) is a point on the graph of the line, find the missing coordinate. y1=? And if (x2,1) is a point on the graph of the line, find the missing coordinate. x2=?
2x - 3y = - 3
Substitute - 3 for x and find y, which is the same as:
Apply the same concept for the 2nd part, and you should be able to find x, which is the same as: .
