Question

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

Answer 1

Answer:

$y=-2x-2$

Step-by-step 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

$y=-2x-2$
