A formula in the form y = mx + b models the value, y, of a new car x years after the initial purchase in 2017. Would you expect m to positive, negative, or zero?
Slope, m, would be negative.
As the amount of time increases {the x-axis},
the value of the car would decrease {y-axis}
Or, in terms of rise over run, as the line runs to the right on the x-axis, it falls on the y-axis.
