If you seek success...I am here to help
When the slope is UNDEFINED, that means the denominator of the slope formula is ZERO
Slope formula = (y2 - y1)/(x2 - x1),
and the graph is a VERTICAL line and the equation of the line is x =7
Point (7, -4) is a point on the line.
Hope this helps...

An undefined slope is a vertical line and can only pass through the x-axis. Look at your point, a vertical line will pass through the point at x=7. 👍🏻
