Elaine has $50 on her lunch card. Each day she spends $3 on lunch. Which table has a greater rate of change than the function that represents how much is left on Elaine’s lunch card?

x y
50 72
51 69
52 66

x y
25 9
26 8
27 7

x y
13 50
14 40
15 30

x y
7 21
8 12
9 3

step-by-step explanation:

you divide the denominator by the numerator on both sides and if the quotients are equal then the fractions are equivalent

0 is its x and y coordinate

options a,b,c are the right answer.

step-by-step explanation:

a linear parent function is always represented as y = x

if we write this function in the form of y=mx+c

⇒

or  

now if we plot a graph we will find these characteristics:

1) y intercept of the graph is zero so its a straight line passing through origin.

2) as we can see in both the forms of function written, values of x and y may be either positive or negative for the positive slope means points on the graph are either in first quadrant or in third one.

3) it's slope is one.
