Question 636430: I Really Need Help! It's Friday and i have tons of homework! I need help with Find the value of x or y so that the line passing through the two points has the given Slope! PLEASE EXPLAIN THIS STEP BY STEP, I SUCK AT MATH
Problem: ( -3 , y ), ( -9 , -2 ); m = 1
also ( 7 , 5 ), ( x , 2 ); m =

You can put this solution on YOUR website!

First of all, stop typing in caps. It's the equivalent of shouting!!
Slope form: 
Since slope = 1, then we can say that: 
Now, substituting coordinates, (- 3, y) and (- 9, - 2), we get:
- 2 – y = - 6 ----- Cross-multiplying
- y = - 6 + 2
- y = - 4
y =  , or 
You can apply the same concept when doing the 2nd problem.
