Question 108405This question is from textbook McDougal Littell Algebra 1
: what is y when (2, y), (4, 5), m= 2
what is y when (-5, 3), (3,y), m= -1/2
what is y when (-1, 5), (3,y), m= 5
what is y when (5, 7), (8, y), m= 4/3
what is y when (2, -15), (5, y), m= 4/5 This question is from textbook McDougal Littell Algebra 1

You can put this solution on YOUR website!
slope=(y2-y1)/(x2-x1)
2=(5-y)/(4-2)
2=(5-y)/2 now cross multiply
4=5-y
-y=4-5
-y=-1
y=1 answer.
That's how it's done.
I'll leave the rest for you to master.
