Select the shape of the graph of x=−4 and its correct slope from the selections below.
a. Vertical Line; m=undefined
b."V" shaped graph, opening downward, shifted up 1.
c.Vertical Line; m=0
d.Horizontal Line; m=0
x = -4 means that a vertical line is drawn through the point (-4, 0) on a graph. This creates a vertical line with a slope of zero. Remember that if a line doesn't increase or decrease then the slope is 0.
