Somebody me! my grade is struggling so say the correct answer.

1. (a) y = 0.50 x+ 15

1. (b) The graph is a straight line

1. (c) Slope = 0.50; y-intercept = (0, 15)

Step-by-step explanation:

1. (a) The equation

There are two variables: the total rental cost (y) and the distance travelled (x).

The total rental cost depends on the distance travelled.

The initial cost is the $15 flat fee.

The rate at which the cost increases is $0.50/mi.

The equation for the relationship iss then

y = 0.50x + 15

===============

1. (b) The graph

The graph of the equation is a straight line on a coordinate plane (see below).

It shows that the cost starts at $15 and increases at a constant rate.

===============

1. (c) The slope and y-intercept

The y-intercept is the point at which the graph crosses the y-axis: (0, 15).

The equation for the slope is

Slope = (y₂ - y₁)/(x₂ - x₁)

Let’s pick the points

x₁  = 10,  y₁ = 20

x₂ = 90, y₂ = 60     Calculate the slope

Slope = (60 – 20)/(90 – 10)

Slope = 40/80

Slope = 0.50

The y-intercept represents the $15 flat fee and the slope represents the rate of $0.50/mi.

may i see the picture? it would a lot, xox

50- 250 is correct i did that one too
