Question

Graph the equation and interpret the slope.

The cost y in dollars of buying x movie tickets is represented by the equation y = 10x.

Answer 1

The graph is in the image at the end, and the slope means that each movie costs 10 dollars.

How to graph this equation?

Here we want to graph the linear equation:

y = 10x

To do so, we first need to find two points that lie on the line.

if x = 0, we have:

y = 10*0 = 0

if x = 1, we have:

y = 10*1 = 10

Then we can use the points (0, 0) and (1, 10), now we can plot these points and connect them with a line.

And the slope of this line is 10, which means that each movie costs $10.
