Sagot :
Answer:
A
Step-by-step explanation:
given the points
(0, 0 ) , (2, 4 ) , (4, 8 )
note that the y- coordinate is twice the value of the x- coordinate , so
y = 2x
Answer is A. y= 2x.
Reason.
Your slope (the number next to x in slope intercept form) is 2.
You know this by looking at your graph. From one point (2,4) to (4,8) you go up y + 4 and go right x + 2.
Slope is rise over run or y over x, so 4/2 or 2.
You can also find slope by finding change in y over change in x.
(y2 - y1) over ( x1 - x2)
(8-4) over (4-2) = 4/2 or 2.
So y = 2x.
Problem solved!
