Ellie designed and constructed a model of a theme park. In her model, 1 inch represents 25 feet. If the tallest rollercoaster in the theme park will have a peak of 475 feet, how tall should the peak be in her model?

b.an increase in a causes b to decrease

  y= -3x is the required function.

step-by-step explanation:

we have been given a table:

x             y

0             0

1             -3

3             -9

-2             6

we can see that the values of y is -3 times the value of x

hence, the function would be: y= -3x.

put the values of x will give the same y as in the table that means function is satisfying the given table.

y = 5x + 17

step-by-step explanation:

a perpendicular line will be the opposite reciprocal slope of the given equation.   the slope given is -1/5 so the opposite reciprocal is 5

find b:

7 = 5 (-2) + b

7 = -10 + b

17 = b

write equation

y = 5x + 17

i suppose it should be (y=2x-5)
