Question4. A random sample of people was asked to report the age and distance driven of their first car. A line was fit to the data to model the relationship.
Write an equation of the line of best fit in $\mathbf{y}=\mathbf{m x + b}$ : Steps:
1. Identify $y$-intercept (where the line crosses the y -axis) y -intercept, $\mathrm{b}=(\mathrm{O}$, $\qquad$ )
2. Identify another point on the line (it has to be on the line)
2nd point ( $\qquad$ , $\qquad$ )
3. Find slope, $m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}$ between these two points $\mathrm{m}=$ $\qquad$ $=$
4. Substitute $m$ and $b$ values into $y=m x+b$ $y=$ $\qquad$
