Look at this function: x y −3 −8 −2 −6 −1 −4 0 0 matt said that the function is linear. justine said that the function is nonlinear. which of the following explains who is correct? matt, because for every 1-unit increase in x, there is an increase in y by 2 matt, because for every 2-unit increase in x, there is an increase in y by 1 justine, because the point (−3, −8) does not lie on the straight line that contains the other points justine, because the point (0, 0) does not lie on the straight line that contains the other points

Justine is correct, because the point (0,0) does not line up with the straight line that contains the other points.

Step-by-step explanation:

From points (-3,-8), to (-1,-4) the points make a straight line because the x coordinates increase by 1 while the y coordinates increase by 2. Up until the last y coordinate. While the x coordinate follows its pattern, the y coordinate increases by 4 when it's supposed to increase by 2.

Note:

Good luck with your quiz, hope I helped!

connie < felicia < stew

step-by-step explanation:

stew:

we need to find the slope

m = (y2-y1)/ (x2-x1)

    = (2650-795)/(10-3)

    = 1855/7

connie:

we need to find the slope

m = (y2-y1)/ (x2-x1)

we have two points (0,0) and (4,800)

m = (800-0)/(4-0)

  m = 800/4

i believe the correct answer is b.
