Question

I need help with example 4 plz

Answer 1

a)
`y=1`

b)
`x=-3`

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`
