Is (2,10) a solution of the equation y = 9x

This line is already in slope-intercept form.

The slope of the line is 9, and the y-intercept is 0.

Because of this, we can find every y value for any x value simply by replacing x with the value of the x coordinate.

By replacing x with 2, we can see what the y coordinate would be when x is 2.

9(2) = 18

The y value would be 18, which is not 10, meaning (2, 10) is not a solution to the equation.

They arrive at the same time.

Step-by-step explanation:

If Alison spends 3 seconds to cover the last 1/4, it means that in 12 seconds will cover the four quarters because the acceleration is constant.

On the other hand Kevin spends 4 seconds to cover the last 1/3 of the distance, it  means that in 12 seconds will cover three thrds.

Finally we can conclude that both of them spend the same time to cover the drag race.
