All three of them do exist on the line y = 2.5x + 4
In order to find the answer to this question, start by finding the line for two points. For this example, we'll use A and C.
First we need to find the slope.
(y1 - y2)/(x1 - x2)
(9 - -1)/(2 - -2)
(9 + 1)/(2 + 2)
10/4
2.5
Now using slope intercept form and point A, we can determine the intercept of that line as well.
y = mx + b
-1 = 2.5(-2) + b
-1 = -5 + b
4 = b
So now we know A and C form the line y = 2.5x + 4. We can then check if B fits that line.
y = 2.5x + 4
4 = 2.5(0) + 4
4 = 0 + 4
4 = 4 (TRUE)
Therefore, it also falls on that line.

Answer:
A = 6 x 7
Step-by-step explanation:
To find the area of a parallelogram we use the equation of Area = base x height. In this case since the base is 6 and the height is 7, we plus in these numbers for the variables (b x h) to get the area.
