A. Mark a point at 8 on the y-axis, move upward 2 and right 1, mark the point and draw the line.
B. Mark a point a -2 on the y-axis, move downward 8 and right 1, mark the point and draw the line.
C. Mark a point at 8 on the y-axis, move downward 2 and right 1, mark the point and draw the line.
D. Mark a point at -2 on the y-axis, move upward 8 and right 1, mark the point and draw the line.

Answer 1

First, looking at the answers, do you want to mark a point at 8 or -2 on the y-axis?

Answer 2

a point a 8 @BangkokGarrett

Answer 3

Yes. so it's either A or C. Do we want to move generally upward from there as we move to the right or downward ?

Answer 4

Look at the slope. Do you know the slope?

Answer 5

downward? @BangkokGarrett so the answer is C?

Answer 6

that's right!

Answer 7

@BangkokGarrett ok thanks! :)
