Answer:
C it has the largest rate of change
Step-by-step explanation:
To find the greatest rate of change, we need the largest slope
In equation form y =mx +b where y is the slope
A. 6x – 7y = 21
Solve for y
Subtract 6x from each side
-7y = -6x+21
Divide by -7
y = 6/7x + 21/7
The slope is 6/7
B. y = 2x – 2
The slope is 2
C. x 2 3 4
y 7 13 19
slope = (y2-y1)/(x2-x1)
= (19-7)/(4-2)
= 12/2
=6
D. A linear function that goes through point 1, 2 and point 0, negative 1
(1,2) (0,-1)
slope = (y2-y1)/(x2-x1)
= (-1-2)/(0-1)
= -3/-1
=3
