Question

How do I right an equation of of this please help

Answer 1

In this problem, we have a horizontal line

that means

the slope is equal to zero

m=0

the equation of the line in slope-intercept form is equal to

y=mx+b

m=0

so

y=b

the y-intercept is b=-7 (looking at the graph)

therefore

the equation is

y=-7
