Question

y=3x-1

y=-2x+4

Answer 1

y=3x-1 is an upward sloping straight line with slope =3, y intercept =-1

x intercept = 1/3

plot the points (0,-1) and (1/3, 0), connect them with a line

y=2x+4 is an upward sloping straight line with slope =2, y intercept=4

x intercept =-1

plot the intercepts, connect them with a straight line
