Average rate of change is the same as finding slope between a line on a non- linear function.
Using the ordered pairs
(5,10) and (8,1)
(10-1)/(5-8) = 9/-2 = -9/2

Which is an equation in point-slope form for the given point and slope? Point:(2,-6) Slope:-3/4
Fynjy0 [20]
The equation for point-slope form is 

y-y_{1}=m(x-x_{1})

m being the slope, y1 being the second point in the (2, -6) and the x1 being the first point in the (2, -6).

So the equation would look like this (for point-slope):

y-(-6)=- \frac{3}{4}(x-2) \\ or \\ y+6=-  \frac{3}{4}(x-2)

If you're looking for slope-intercept form you can simplify the equation:

y+6=- \frac{3}{4}(x-2) \\  \\ y+6=- \frac{3}{4}x+ \frac{6}{4} \\  \\ y+6-6=- \frac{3}{4}x+ \frac{6}{4}-6 \\  \\ y=- \frac{3}{4}x- \frac{18}{4}

If you're looking for the standard form of the equation, you can take the slope-intercept equation and turn it into standard form:

y=- \frac{3}{4}x- \frac{18}{4} \\ 4y=4(- \frac{3}{4}x- \frac{18}{4}) \\ 4y=-3x-18 \\ 4y+3x=-3x-18+3x \\ 4y+3x=-18 \\ 3x+4y=-18

She Spent $115 For The Pots And Pans.

3/5 Of $250 = $150
50 • 3 = 150
50 • 5 = 250
150/250 = 3/5

$150 - $35 = $115
