The equation in point-slope form for a horizontal line that passes through (-4,-1) is y = -1

Solution:

Given that, a horizontal line that passes through (-4,-1)

If a line is horizontal, then the slope is 0

A horizontal line has slope 0 because all its points have the same y-coordinate

The equation of line in point slope form is given as:


y - y_1 = m(x-x_1)

Where, "m" is the slope of line

Here, m = 0

Thus the equation becomes:


y - y_1 = 0

Given point is (-4, -1) .Substitute
y_1 = -1


y - (-1) = 0\\\\y + 1 = 0\\\\y = -1

Thus the equation in point-slope form for a horizontal line that passes through (-4,-1) is y = -1
