Find the slope of (7, 9) and (2, 12)

The slope of the line that goes through two points and is:

The two points we are given is (7,9) and (2,12). Substitute these values into the formula for the slope

Simplify

Simplify again

This should be your answer. Let me know if you need any clarifications, thanks!

for finding the midpoint of any given 2 pair of points simply add the respective x coordinates with other x coordinate and the y coordinate with other y coordinate and divide them by 2

in your question it will be :

(3+1)/2 for the x coordinate of mid point i.e 2

[8+(-4)]/2 for the y coordinate of midpoint i.e 2

so coordinates of mid point of points (3,8) and (1,-4) will be (2,2)

1.3

step-by-step explanation:

3x2=6   9x+6

bring down the 6 on both sides

6+6=12

12= 9x

divide by 9

12/9 =

1.3 =x
