Plz help me Question 1(Multiple Choice Worth 1 points)

(4.02 MC)

Tom and Jack spend a certain amount of money from their accounts each week at a pet shelter.

The table shows the relationship between the amount of money (y) remaining in Tom's account and the number of weeks (x):

Function 1:

Number of Weeks
(x) Amount Remaining (dollars)
(y)
1 60
2 53
3 46
4 39

The equation shows the relationship between the amount of money, y, remaining in Jack's account and the number of weeks, x:

Function 2:

y = –8x + 60

Which statements states and explains which function shows a greater rate of change?
Function 1, because Tom spends $7 each week and Jack spends –$8 each week
Function 1, because Tom spends $21 each week and Jack spends $52 each week
Function 2, because Jack spends $60 each week and Tom spends $21 each week
Function 2, because Jack spends $8 each week and Tom spends $7 each week
Question 2(Multiple Choice Worth 1 points)

(4.05 LC)

Which of the following is a linear function?

An xy coordinate plane is drawn. A parabolic curve that opens down is drawn. The vertex of the curve is on the axis.
An xy coordinate plane is drawn. A straight line going below the origin from the second quadrant to the fourth quadrant is drawn.
An xy coordinate plane is drawn. An ellipse is drawn on the axis and partially cutting the y-axis.
An xy coordinate plane is drawn. A straight line starts from the y-axis and slants down to a certain point in the first quadrant, then down again with a different slope, and then down again at another slope. All the line segments are straight lines in the first quadrant.
Question 3(Multiple Choice Worth 1 points)

(4.05 MC)

The graph shows a journey in a car. Which of the statements most likely describes the start of the journey at the portion of the graph labeled I?

A line graph is drawn on the first quadrant of a coordinate plane. The x-axis is labeled Time in seconds, and the y-axis is labeled Distance in miles. The line graph is divided into 7 segments labeled I, J, K, L, M, N, and O. I starts at the origin and is a straight line slanting up. J is a line segment that starts at the end of I and is horizontal. K is a curve that starts at the end of J and curves up. L is a straight line that starts at the end of K and is horizontal. M is a straight line that starts at the end of L and slopes down. N is a straight line that starts at the end of M and is horizontal. O is a curve that starts at the end of N and curves down to finally touch the x-axis.

The car travels the same distance per unit of time because the portion shows a linear, increasing function.
The car travels different distances per unit of time because the portion shows a linear, increasing function.
The car travels the same distance per unit of time because the portion shows a nonlinear, increasing function.
The car travels different distances per unit of time because the portion shows a nonlinear, increasing function.
