Question

Help please!! the ones with the X’s on the question numbers do not need to be answered! :)

Answer 1

me need slope and y intercept to get it in y=mx+b form (slope intercept)

Slope is the

difference in y / differences in x

differences in y = 6.5 -3  = 3.5  

difference in x = 2 - 1 = 1

so slope is 3.5/1 or just 3.5

(now you can see the answer is c but lets check it by getting the y intercept too)

y intercept

this is when x is 0

the lowest x we see is 1 so if I go bacl to 0 in x the y must for back 3.5

3-3.5 is -0.5

so equation is y=3.5x -0.5 so the closest is c
