Question

Can someone help with one question?

Answer 1

Can you pick two points on this graph that are easy to read and write down their coordinates?

Answer 2

(0, 1) ?

Answer 3

Good. That's one point. Can you choose another one?

Answer 4

First find the slope of the line given

m = slope = rise/ run

pick two obvious points on the graph and find the slope between them.

(0,1) and (-3,5) seems to be the easiest

the slope between these two is -4/3

for a perpendicular slope you just flip the slope and change the sign

opposite reciprocal

Answer 5

So 3/4 ?

Answer 6

you got it

Answer 7

Did you understand how the slope was calculated?

Answer 8

Yes, thank you!

Answer 9

Can you help with one more?

Answer 10

First check that every graph contains the point (-4, 2)

Answer 11

the easiest way to solve this one is to plot the first point and navigate the second one with the slope

so (-4,2)
