In order to find the equation, they're is 2 ways of doing. Plugging in or using Y-Y1=M(X-X1). For plugging in, replace the x with 1 x value and plug in y for the corresponding x value. Or you can plug in all the x and y values into the equation shown and put the number on the left to the right and you'll get your equation immediately. Good luck on the Quizziz!
Looking at the answer choices, at first glance you see x=0 and y=5, this mean the y-intercept is 5. And in the equation y=mx+b, positive 5 will go into b.
The only answer with +5 as y-intercept is y=x+5
Now what if there are multiple +5 for y-intercept?
If there is multiple +5, you will also need to find the slope, you can find the slope by using
Charge per day = $90 / 15 = $ 6 <span>Charge per year = $ 6 * 365 1/4 ( If the year contains 365 1/4 days) </span> <span>= $ 2191.5 </span> <span>As a percentage = 2191.5 / 1460 * 100 = 150 % So the answer should be 150%</span>
