Explanation Given information: The rate of fatalities (per hundred million vehicles-miles) from automobiles for the years from 2001 to 2009 is given by the equation y = − 0.06 x + 1.7 , where x is the number of years after 2000 . The rate of fatalities (per hundred million vehicles-miles) from light trucks for the years from 2001 to 2009 is given by the equation y = − 0.08 x + 2.1 , where x is the number of years after 2000 . Calculation: As per the given information - The rate of fatalities (per hundred million vehicles-miles) from automobiles for the years from 2001 to 2009 is given by the equation y = − 0.06 x + 1.7 , where x is the number of years after 2000 . The rate of fatalities (per hundred million vehicles-miles) from light trucks for the years from 2001 to 2009 is given by the equation y = − 0.08 x + 2.1 , where x is the number of years after 2000 . Writing these as system of equations- { y = − 0 To determine (b) The fatality rate per million vehicles-miles for each category of vehicle.

Equations and Inequations

Equations and inequalities describe the relationship between two mathematical expressions.

Linear Functions

A linear function can just be a constant, or it can be the constant multiplied with the variable like x or y. If the variables are of the form, x2, x1/2 or y2 it is not linear. The exponent over the variables should always be 1.
