10a. The y-intercept of the estimated line of best fit is at (0,b). Enter the approximate value of b. Round your estimate to the nearest whole number. 10b. Enter the approximate slope of the estimated line of best fit in the second box.

Count the rise and run to find the slope, 1. Next, find the y-intercept-(-1). Now make the slope-intercept equation-  y = 1x - 1. Double check, put x = 2 in the equation-  y = 1(2) - 1 (=) y = 2 - 1 (=) y = 1.

So, the slope-intercept equation for this line is y = 1x - 1.
