What is the distance between parallel lines whose equations are y = 2x + 7 and y = 2x – 3?

The distance is or .

Step-by-step explanation:

Slope of parallel: 2

Slope of perpendicular: -1/2

Pick a point for y =2x + 7. For example (0,7)

Use the perpendicular slope to get to the other line to find the other point of y=2x-3. Look at the screenshot...I got (4,5).

Distance formula

Insert (0,7) and (4,5)

=

answer:

c) the x-coordinate of the center of the circle increases by 3
