Question

What is the y-coordinate of point b if the slope of line ab is 5. B(3,y). A(2,4)

I added 3+2=5 and added +4=9 is this right

Answer 1

So we are just randomly adding a bunch of numbers that we see ??
I think you knew that the answer was supposed to be 9, so you just "did something" with the 4 numbers given that produced 9.
If not, please explain why you added 3+2+4 ?

correct way:

slope is 5, point on line is (2,4)

equation of line is:
y-4= 5(x-2)

for your 2nd point, sub in x = 3, and solve for y


or:
(y-4)/(3-2) = 5
y - 4 = 5
y = 9

Answer 2

I added from a and b 3+2=5 and the 4 was left then added =4=9. I really didn't know what I was doing your right I just didn't know =4 was left it was just a guess

Answer 3

So what is the answer

Answer 4
