As head of the park Department, Jada has been tracking the park's use of different supplies over the last several years. Her research shows that, up though last year, the park's total water usage per year was 13,505 gallons for all regular days, plus another 18.5 gallons for each special event hosted by the park. How many special events did the park host last year?

x = -2

y = 848

step-by-step explanation:

plug in the numbers

not sure but it may be b, as i said i'm not sure.

y = 3x+4

step-by-step explanation:

to find the slope

slope = (y2-y1)/ (x2-x1)

    = (-8-4)/ (-4-0)

    = -12/-4

  = 3

using the slope intercept form of a line

y= mx+b

we know the slope is 3

we know the y intercept is 4 ( the point where it crosses the y axis or x=0)

y = 3x+4

y=-2x+1500

step-by-step explanation:

+1500
