# Thread: Slope/midpoint of the line

1. ## Slope/midpoint of the line

Can someone help me find the midpoint of the line segment joining (4,8) and (-2,-6)? Also, find the slope of the line joining the points A (-3,2) and B (0,4) Thanks!

2. The midpt. of a line with coo'rds $(x_1, y_1)$ and $(x_2, y_2)$ is

$(\frac{x_1+x_2}{2}, \frac{y_1+y_2}{2})$

Slope of a line with aforementioned coo'rds is

$\frac{y_2-y_1}{x_2-x_1}$

Jay1,

Go back and study your formulas. These questions are easy if you know them. You need to learn these.

MIDPOINT FORMULA:

$M=\left(\frac{x_1+x_2}{2}, \frac{y_1+y_2}{2}\right)$

SLOPE FORMULA:

$m=\frac{y_2-y_1}{x_2-x_1}$

4. Yes, jay1, you have asked a series of questions that depend only on basic definitions and formulas. Do you not have your text book with you to look up the formulas? I hope you are not using this forum as a way of avoiding looking things up yourself!
