Which formula gives the coordinates of the midpoint of the segment connecting points (a, b) and (c, d)

17

Step-by-step explanation:

1232

i think it is c

Step-by-step explanation:

which expression represents the approximate length of bc?

step-by-step explanation:

b. y = 4x - 2

step-by-step explanation:

to find a parallel equation to an equation, make sure both equations have the same slope but different y-intercepts.

y = 4x + 1

4 = slope

1 = y-intercept

y = 4x - 2

4 = slope

-2 = y-intercept

they both have the same slope but different y-intercepts, so, b. is the correct answer.

and to check your work, you can graph both equations. : )
