Question

Find an equation of the line described. Store the equation in slop-intercept form when possible.

Through (-7, -5), perpendicular to the y-axis.

I could use some help figuring out this problem. I have no clue where to start.

Answer 1

Y = -5

Explanation:

The line needs to be parallel to the y-axis, which means it forms a 90° angle with the y-axis. This means the line we are looking for is a straight horizontal line. The line must pass through the point (-7, -5), but we can disregard the x value since we figured out that the line is perfecly horizontal, so it has no x value. The answer we are left with is y = -5, which is a horizontal line across -5 on the y axis.

Hopefully you can understand my explanation :)
