d. -2

Answer 1

slope formula
\[\Large m = \frac{y_{2}-y_{1}}{x_{2}-x_{1}}\]

- -------
4 - (1)

= 4/5

Answer 3

i am confused here

Answer 4

at this part i mean

Answer 5

In english:
Step 1) subtract the y coordinates
Step 2) subtract the x coordinates (same order as you did y)
step 3) divide the y difference (from step 1) over the x difference (in step 2)

Answer 6

you should have 4 - (-1) in the bottom

Answer 7

yeah i do i forgot the negative here one sec

Answer 8
