Question

Will the ordered pairs listed in the table form a straight line when plotted? Explain your reasoning.
x y
-8 -1
-2 3.5
10 12.5
20 20

Answer 1

Answer:

Yes.

Step-by-step explanation:

If the slope between successive points have the same slope then they will form a straight line.

Slope = ( 3.5- -1) / (-2 - -8) = 4.5/6  = 3/4

Slope = (12.5 - 3.5) / (10 - -2) = 9 / 12 = 3/4

Slope = (20-12.5)/(20-10) - 7.5/10 = 3/4 .

So the answer is yes.
