Find the slope intercept form for (2,4) (10,5)

As we move from the first point to the second, x increases from 2 to 10, so the change in x is 8.  At the same time, y increases by 1 from 4 to 5.  Thus, the slope is m = rise / run = 8/1 = 8.

Using the point-slope formula, we get y-4 = 8(x -2), or 8x - 16.

Isolate y.  To do this, add 4 to both sides, obtaining:

y = 8x - 12.  

This is the slope-intercept form for the equation of the line thru (2,4) and (10,5).

question 1 is 8, question 2 is 9, question 3 is 24

step-by-step explanation:

now, the numbers they give you at the top are the key. from there, you just have to plug and chug! let's try 1, 2, and 3!

key: a=3, b=5, c=6

1. a+5

remember, a=3, so we plug that in to get 3+5=8

2. 15-c

c=6, so we plug that in to get 15-6=9

3. 4b

b=6, so we plug it in to get 4*6=24

time to try the rest on your own! if you put the answers below in a comment, i'll check them for you!
