Question

Find the slope and write an equation of the line which passes through the points. (−3, 9) and (−3, −5)

Answer 1

Answer:

Slope: undefined

Equation: x=-3

Step-by-step explanation:

To find the line that passes through the points, you first want to find the slope.  The formula for slope is $m=\frac{y_2-y_1}{x_2-x_1}$. Once we have the slope, we can use any given point to plug in to find the y-intercept.

$m=\frac{-5-9}{-3-(-3)} =\frac{-14}{0}$

We can see that the slope is undefined. If we look at the point, we notice that they both have the same x-coordinate. This let's us know that the equation is x=-3.
