Question

I need help with example 4 plz

Answer 1

Answer:

a) $y=1$

b) $x=-3$

Step-by-step explanation:

Recall the forms of vertical and horizontal lines

Horizontal lines come in the form of $y=0x+b$, so the slope of the equation is zero. The value of b will be the y-value of the point that  you're given.

This means that the equation for a would be y=1

Vertical lines come in the form of $x=a$. For this line, the value of a would be equivalent to the x-value of the given point. Therefore, b. would be $x=-3$
