Y=-x+9; (-9, ),(1, ),(5, )

(-9,18) , (1,8)  and (5,4)

Step-by-step explanation:

If  the x coordinate is -9 then plot it into the equation and solve for y.

y = -1(-9) + 0

y = 9 + 9

y = 18

Same for the second one plot in the value of x and solve for y

y= -1(1) + 9

y = -1 + 9

y = 8

Again same for the last one

y = -1(5) + 9

y = -5 + 9

y = 4

i assume that by 5 you mean 5 gallons.

(20)(0.25) = 15

removing 15 gallons reduces the tank from 20 to 5.

first one is a: renaming a fraction. second one is c: de-c
