Scatter plots line of best fit

I can do most of the problem but how do I find the y-intercept if it is now shown on the graph

David W.

Can you develop an equation from the scatter plot? Remember that x = 0 on the y-axis, so if you have an equation, f(0) is your y-intercept.

I agree with David. Find the slope of the line, m, and set y=mx+b. Use a known point that you can see lies on the line, (x,y) and put it into the equation to find b, the y-intercept.
