Match each item in column a to an answer in column b. is each situation a linear or a nonlinear model?

1. Non-Linear. This is a quadratic equation which produces a curved parabola. 

2. Linear. The graph is a straight line. The equation is in the form y = mx+b where m = 0.04 and b = 1200. Replace x with s if you need to. Replace y with e if you need to.

3. Non-Linear. This is an exponential graph. It curves downward forever due to the base 0.2 being less than 1. It will slowly approach the asymptote y = 0

4. Linear. Similar to number 2 above. We can write the equation in the form y = mx+b where m = -42 is the sloe and b = 368 is the y intercept. 

A5 miles because when you look at the chart count how many times it goes into it i don’t even know wha,t i’m saying anymore mpbut long stor6 short it’s 5 miles
