x = 4 is a straight line that is vertical when plotted on the xy graph, where y is the vertical axis and x is the horizontal axis. A vertical line has an infinite slope; the slope is infinity
The equation of a line with an undefined slope is x = a.

Point: (-3, 4) Slope: 2 Equation: y-4 = 2(x--3) => y = 2x+10
y+ 4= -2( x-2 )
