Which best describes the equation that the graph represents?

On a coordinate plane, the x-axis is labeled time (in minutes) and the y-axis is labeled distance (in kilometers). The point (5, 9) is plotted on a line that goes through (0, 0).

y= x

Step-by-step explanation:

Given the two points:

Because the x-axis is labeled time (in minutes) and the y-axis is labeled distance (in kilometers).

=>Time, x the independent variable,and distance is the dependent variable.

We have the standard form of a linear equation is:

y= mx + b where a is the slope

We know that, the slope of the function is:

m =

In this situatuon, m =

=> y= x + b(1)

The line that goes through (0, 0) so we substitute (0, 0) into (1), we have:

0 = *0 + b

<=> b = 0

So our equation that the graph represents is: y= x

answer: about 22.67
