2.A quarry runs a delivery service for crushed stone. The cost to deliver the crushed stone is a flat fee for the delivery and the cost of the crushed stone in terms of weight. The graph of the total cost, C, in dollars as a function of the weight, x, in pounds of the crushed stone is shown. What is the meaning of the y-intercept?

A line is graphed on a first quadrant coordinate plane. The horizontal x-axis is labeled Weight in pounds and goes from 0 to 6000 in increments of 200, and the vertical C of x-axis goes from 0 to 500 in increments of 20. The line passes approximately through (0, 120) and (400, 134).

A.The cost of the delivery is \$120.

B.The cost of stone dust is \$0.035 per pound.

C.The cost of the delivery is \$70.

D.The cost of stone dust is \$70 per ton.

3.What is the x-intercept of the function f(x) graphed on the coordinate plane?

A line is graphed on a four quadrant coordinate plane. The horizontal axis goes from negative 7 to 7 in increments of 1, and the vertical axis goes from negative 7 to 7 in increments of 1. From left to right, a straight line passes through (0, 1) and (2, 0).

4.The graph of the function g(x) is shown on the provided coordinate plane. Which statement is correct about the function g(x)?

A function is graphed on a four quadrant coordinate plane. The x-axis and the y-axis go from negative 6 to 6 in increments of 0.5. A line passes through (negative 2, 0) and (2, 3).(1 point)

A.The value of g(x) increases by 4 when x increases by 4.

B.The value of g(x) is 0 when x=2.

C.The value of g(x) decreases by 4 when x increases by 4.

D.The value of g(x) is −2 when x=0.

1. The line passes through (0, 7) and (4, 2).
so, the slope is (2-7)/(4-0) = -5/4
Just for further information, that means the equation of the line is
y-2 = -5/4 (x-4)
or
y = -5/4 x + 7

See what you can do on the other. They are similar.
