Question

The cost y (in dollars) of a gym membership for x months is y=20x+25. Graph the equation.

Answer 1

The graph of the equation y = 20x+25 is attached below.

Please check the attached graph.

Explanation:

We know that the slope-intercept form of the line equation

`y = mx+b`

where

• m is the slope

• b is the y-intercept

In our case, we are given that the cost y (in dollars) of a gym membership for x months is:

`y=20x+25`

comparing with the slope-intercept form of the line equation

Here:

The slope of the equation is: m = 20

The y-intercept is: b = 25

The graph of the equation y = 20x+25 is also attached below.

From the graph, it is clear that the graph of the line crosses the y-axis at y = 25.

Thus, the point (0, 25) represents the y-intercept of the function.
