Question

The equation y=1.25x+12 represents the total cost, y, in dollars, for using a taxi service to travel a distance of x miles. Which graph best represents the equation?

Answer 1

The graph that represents the equation is in the image attached.

How to determine the graph that represents equation?

The graph that represents the equation is determined by considering the following:

• The slope of the graph, and
• The y - intercept of the graph

The given equation;

y = 1.25x + 12

The general equation of linear function is;

y = mx + c

where;

• m is the slope of the function
• c is the y - intercept of the function

If we compare the general equation of linear function with the given equation, we can see that;

slope, m = 1.25

y - intercept = 12

Thus, the graph that represents the equation is in the image attached.
