1.) Formula for rate of change is (First value of x - Second value of x)/(First value of Y - Second value of Y). So now, all we have to do is plug in the values. (1 - 3)/(0 - 4). After solving this, we get - 1/2.
2.) 1st box is y = 1/2x+5/12
2nd box is y =-4/5x+4
3rd box is -1/2x - 7
3.) Y intercept is the original height of the candle in centimeters. Slope is the change of the height of the candle in centimeters per minute.
