The following graph is not linear, exponential, or quadratic. Explain why.

It is not linear because it isn't a straight line.It isn't exponential because it doesn't have a constant rate of change. It isn't a quadratic equation because it can't be made into a simple form.

Hope this helps:)

x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x

step-by-step explanation:

last month maria hiked the 5-mile mountain trail a number of times and she hiked the 10-mile canal trail several times. let x represent the number of times she hiked the 5-mile trail, and let y represent the number of times she hiked the 10-mile trail. if she hiked a total of 90 miles, which equation can be used to find the number of times maria hiked each trail? x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x

i believe that the answer is

b. y-1=-2(x-4)

hope this !
