Algebra 2 problem help

Solve for the variable using slope formula: (9,X) (2,3) slope = 3.

Thank youuuuuuu (:

The slope m of the line containing the points (x1,y1) and (x2,y2) is given by
m = (y2 - y1) / (x2 - x1).

In this case, the points are (9,X) and (2,3), and the slope is 3, so we have:
3 = (3 - X) / (2 - 9)
(3 - X) / -7 = 3
3 - X = -21
X - 21 = 3
X = 24

Hope that helps :)

(3-x)/(2-9)=3
(3-x)/-7=3
3-x=-21
-x=-7
x=7

that's just the work step by step. hopefully that'll refresh how to do this

(3-x)/(2-9) = 3
3-x = -21
x = 24

3-x/2-9=3
3-x/-7=3
3-x=-21
3-x=-24
x=24
