Question

Find an equation of the line passing through the given points. Express your answer in slope-intercept form.

(3.8) and (3.-5)

Answer 1

Vertical Lines

There is only one way to represent a vertical line as an equation:

`x=d`

• d = x-intercept

Solving the Question

We're given:

• Line passes through (3, 8) and (3, -5)

Both of the x-coordinates in these points are equal.

This indicates that this is a vertical line.

The x-intercept of a vertical line will always look like
`(x,0)`, where x is the same x-value as the given points.

`x=3`

Answer

`x=3`
