Answer:
An equation is linear if its graph forms a straight line. This will happen when the highest power of x is "1". Graphically, if the equation gives you a straight line then it is a linear equation. Else if it gives you a circle, or parabola or any other conic for that matter it is a quadratic or nonlinear equation.
Step-by-step explanation:
17.99 + 0.83m = 140
0.83m = 140 - 17.99
0.83m = 122.01
m = 122.01 / 0.83
m = 147 <== Mike drove 147 miles
