10) Data for various drivers is displayed below showing the relationship between their age and the furthest distance at which they can read a road sign. The table gives the maximum age, a, in years and the distance, d, in feet. The scatterplot shows the relationship between age and distance.

IMPORTANT: These two points should be on your line and not data points from the table. Do not use the y intercept as a point, because the x axis does not start at zero. Write both coordinates of your points in the blank lines below.

Question
10) Data for various drivers is displayed below showing the relationship between their age and the furthest distance at which they can read a road sign. The table gives the maximum age, a, in years and the distance, d, in feet. The scatterplot shows the relationship between age and distance. a) A d age distance (years) (feet) 23 570 27 520 28 455 40 455 52 455 64 350 65 425 70 375 Sign Legibility Distance (feet) 600 500 400 300 T 15 25 35 45 55 65 Driver Age (years) Draw your line of best fit through the data points. 75 85 b) Pick two points on your regression line. IMPORTANT: These two points should be on your line and not data points from the table. Do not use the y intercept as a point, because the x axis does not start at zero. Write both coordinates of your points in the blank lines below. c) Use your two points from part b to find an equation for your line of best fit. Use the letters a and d in your equation. Do not use the letters x and y. If you end up with decimals in your equation, round to the nearest hundredth. d) Use your equation to estimate the distance at which someone can clearly read a road sign when they are 32 years old.
