Question

Y=-2x+5 was shifted down 7 units what equation is it now

Answer 1

`y=-2x-2`

Explanation:

we have

`y=-2x+5`

This is the equation of a line in slope intercept form

where

`m=-2` ---> the slope

`b=5` ----> the y-intercept

we know that

If the given line was shifted down 7 units, then the new y-intercept is equal to

`b=5-7=-2`

The slope of the new line will be the same that the original line, because are parallel lines

so

The new equation is

`y=-2x-2`
