Slope-intercept form of a linear equation?

Question

I'm having a brain fart, please help J
"Solve for the given variable if the line through the two given points is to have the given slope"
(3,2) and (4,j) m=1
What formula do you use to find J? Is it y1-y2/x1-x2? Thanks in advance! :)

Answer 1

Yes you are correct.
Slope formula m = (y2 - y1)/(x2 - x1)
1 = (j - 2) / ( 4 -3)
1 = j -2
add 2 to each side
3 = j

j = 3
