Plot the following equations using only the two data points. First determine the two (x, y) points, then plot and label the points on a coordinate system, and finally draw the equation line between the points. Try one point where x = 0 and another point where y = 0. If these points coincide, pick another (x, y) point.
y= 4x+ 2 Whenx=0 y=0+2 y=2 Giving point (0, 2) When y = 0 0 = 4x + 2 —4x = 2 x = 2/4 x = 1/2 Giving point (1/2, 0)
