Question

find the equation of the horizontal line that contains the point (-4,8). express the equation using either the general form of the slope intercept form of the equation of a line

Answer 1

Answer:
`y=8`

Explanation:

The equation of the line in Slope-Intercept form is:

`y=mx+b`

Where "m" is the slope and "b" is the y-intercept.

We know that this is a horizontal line. This means that:

`m=0`

Knowing that this line contains the point (-4,8) we can substitute this coordinates and
`m=0` into
`y=mx+b`, and then solve for "b":

`8=0(-4)+b\\\\b=8`

Therefore, the equation of this line in Slope-intercept form is:

`y=(0)x+8\\\\y=8`
