Answer 1

Are you working on regression lines, or a similar topic (prediction,...)

Answer 2

for the 1st one the slope would be -2
you have a change in y of 0.2 but it should be negative

Answer 3

do you see that you wrote 0.2 it should be -0.2
your change in x is ok 1.1 - 1 = 0.1 so slope = -0.2/0.1 = -2

Answer 4

you can use the same approach for the 2nd one
slope = change in y / change in x
match the choice with the correct slope
