Question

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

Answer 1

Slope: undefined

Equation: x=-3

Explanation:

To find the line that passes through the points, you first want to find the slope. The formula for slope is
`m=(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=(-5-9)/(-3-(-3)) =(-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.
