Question
In Exercises 7–10, find the value of $x$ or $y$ so that the line through the pair of points has the given slope.$$\begin{array}{ll}{\text { Points }} & {\text { Slope }} \\ {(-2,3) \text { and }(4, y)} & {m=-3}\end{array}$$
Step 1
We can use the formula for the slope of a line, which is $m = \frac{y_2 - y_1}{x_2 - x_1}$, where $(x_1, y_1)$ and $(x_2, y_2)$ are the coordinates of the two points and $m$ is the slope. Show more…
