Question

How do you find the slope and y intercept for `5y – 2y + 9 = 0`?

Answer 1

`"slope "=0," y-intercept "=-3`

Explanation:

`"simplifying and rearranging"`

`rArr3y+9=0larrcolor(blue)"subtract 9 from both sides"`

`rArr3y=-9rArry=(-9)/3=-3`

`y=-3" is a special line in that it is horizontal and "`
`"parallel to the x-axis passing through all points in the plane"`
`"with a y-coordinate "=-3`

`"since it is parallel to the x-axis the slope "=0`

`"and y-intercept "=-3`

`"the graph of "y=-3" is shown below"`
graph{(y-0.001x+3)=0 [-10, 10, -5, 5]}
