- Slope-Intercept form: y = mx + b, with m = slope and b = y-intercept
The easiest method to find the slope and y-intercept is to convert this standard form equation to slope-intercept form. Firstly, subtract 8x on both sides of the equation:
Next, divide both sides by 12, and your slope-intercept form is:
Now looking at this slope-intercept form, we can see that the <u>slope is -2/3 and the y-intercept is (0, 3/4).</u>
<u><em>Answer:</em></u>
Evans was the fastest
<u><em>Explanation:</em></u>
<u>The relation between velocity, time and distance is as follows:</u>
<u>1- For Cutwright:</u>
We have the time = 84 minutes and the distance = 35 laps
<u>This means that:</u>
velocity = = 0.61667 lap/minute
<u>2- For Evans:</u>
We have time = 96.6 minutes and distance = 42 laps
<u>This means that:</u>
velocity = = 0.43478 lap/minute
<u>3- For Loza:</u>
We have time = 102.6 minutes and distance = 38 laps
<u>This means that:</u>
velocity = = 0.37037 lap/minute
Based on the above calculations, we can note than Evans was the fastest
Hope this helps :)
