Question

How to find the equation?

Answer 1

Know that a line parallel to the x-axis has a slope of 0. To find the equation of the line given the slope and a point on the line, we can use the point-slope equation, which is ($m$ is the slope and ($x_1$, $y_1$) is a point on the line):

$(y - y_1) = m(x - x_1)$

Using the information we know, we can create the equation:

$(y + 5) = 0(x - 8)$

$y - 5 = 0$

$y = 5$

The equation of the line is y = 5.
