Question

Which set of points lies on this graph?


A. (5, 13), (1, 1), (2, -1)
B. (-5, 13), (1, 1), (2, 1)
C. (5, 13), (-1, 1), (2, 1)
D. (-5, 13), (1, 1), (2, -1)

Answer 1

I can see for sure that 2, -1 is on there. So that eliminates b and c

Answer 2

and 1, 1 is on there too. Do you have an equation for the line? I cannot see if 5 or -5 is on the line. You could also figure out the slope to see if it what other point would lie on the line.

Answer 3

im guessing a

Answer 4

Lets make an equation for the line. so y=mx + b right? you can clearly see the y intercept of +3, so that makes it y=mx+3. now you need to figure out m, which is the slope by taking the two points, 1,1 and 2,-1 that are clearly on the line. then you have -2/1 for the slope. so, y = -2/1x + 3. now plug in -5,13 or 5,13 for x and y in the equation and see if it is true. whichever point is true, then that is the correct point for the line!

Answer 5

sorry the equation would be y=-2x+3. so plug 5,13 or -5,13 to see which is true.

Answer 6

d

Answer 7

yep!
