Find the coordinate of the midpoint of the segment with the endpoints at -7 and 4.

9514 1404 393

  -3/2

Step-by-step explanation:

The midpoint has a coordinate that is the average of the end point coordinates.

  (-7 +4)/2 = -3/2

The midpoint of the segment is at -3/2.

if you need just tell me and i will come to the rescue.

step-by-step explanation:

y = 3x+4

step-by-step explanation:

to find the slope

slope = (y2-y1)/ (x2-x1)

    = (-8-4)/ (-4-0)

    = -12/-4

  = 3

using the slope intercept form of a line

y= mx+b

we know the slope is 3

we know the y intercept is 4 ( the point where it crosses the y axis or x=0)

y = 3x+4
