Question

when a tow truck is called, the cost of the service is given by the linear function y = 3x +75, when y is in dollars and x is the number of miles the car is towed. Find and interpret the slope and y intercept of the linear equation.

Answer 1

Answer:

Slope: 3

Y intercept: y = 75

Step-by-step explanation:

The slope of a linear function is the coefficient in front of x. In this case, 3 is being multiplied by x, indicating the slope is 3.

The y-intercept is the y value where the graph of the function crosses the y-axis. In other words, it's the y value when x = 0. To find the y-intercept, simply substitute 0 for x:

$y = 3(0) + 75 \\ y = 75$

We find that the y-intercept is y = 75.
