Marcus plots the point (4, 7) in Quadrant I on the coordinate plane. Nicole then plots the point (4, –3) in Quadrant IV of the same graph. Explain what the line that goes through those two points would look like, and evaluate the slope.

alright well wut hav u gotten so far

AZ · Answer

To find the slope, you can use the slope formula

$\Large\text{Slope} = \dfrac{\color{green}{y_2} - \color{orange}{y_1}}{\color{cyan}{x_2}-\color{red}{x_1}}$

where you have two points
$\Large (\color{red}{x_1}, \color{orange}{y_1})$ and $\Large (\color{cyan}{x_2}, \color{green}{y_2})$

However, there's some general rules you should probably remember about the slope of horizontal or vertical lines:
