The graph ahove shows a line of best fit for data collected on the value of used cars in relation to the
number of years since they were purchased, What is
the equation of the line of best fit?

Follow these steps using the algebra tiles to solve the equation −5x + (−2) = −2x + 4. 1. add 5 positive x-tiles to both sides and create zero pairs. 2. add 4 negative unit tiles to both sides and create zero pairs. 3. divide the unit tiles evenly among the x-tiles. x =
