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: $y=8$

Step-by-step 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:

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