PLEASE HELP!! How do you turn this into an equation in slope-intercept form? Kelly had 4 apples in her kitchen on Monday. On Tuesday, only 1 was left.

    think of slope as a rate of change

    \[\Large \text{slope} = \frac{\text{change in apples}}{\text{change in number of days}}\]

    oh, I get it. So the slope is -3?

    the y-intercept is the amount of apples on the first day

    so the equation is y = -3x + 4?

    yep notice how y = 4 when x = 0 then y = 1 when x = 1
