Question

Write the equation of a line that includes the point (4,-2) and has a slope of 0 in slope intercept form.

Answer 1

For this case we have that the line equation of the slope-intersection form is given by:

$y = mx + b$

Where:

m: It's the slope

b: It is the cut point with the y axis.

In this case $m = 0$

So, we have:

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

We find the cutting point by substituting the y coordinate of the given point:

$b = -2$

Thus, the equation is $y = -2$

ANswer:

Option b

Answer 2

$a. \: y = x + 2$
