Question 1002209
X : 1 3 6
Y: 8 14 13

Okay we need to pick two points so we can find our slope..

I choose (1,8) and (3,14)

Now lets use the equation ysub2-ysub1/xsub2-xsub1

(14-8)/(3-1)

6/2

3

your slope (m) is 3 

slope intercept for is y=mx+b

so we now have our m 

we need b

y=3x+b

to find B

we can pick a random point they have given us

I pick (1,8) again

plug and chug

where x=1 and y=8

8=3(1)+b

see now we can find for b since we only have one variable in that problem

8=3+b

subtract 3

5=b

now we can make our equationnn

y=3x+5 :D
