What is boxed is what you put in your stat plot in your calculator (graphing). To find the y intercept you use the value function on your calculator (if you have a Ti-84 it’s 2nd-> trace-> 1) and enter 0. Yo find the x intercept you use the zero function on your calculator (if you have a Ti-84 it’s 2nd-> trace-> 2 and follow the instructions it asks). Hope this helps!

notice, that, pure juice is 100% juice, dohhh, thus 100/100 = 1.00
50% is 50/100 or 0.50 in decimal format
so..... whatever those two quantities amount to, that is, the 50% and pure juice, or (4)(0.50) + (x)(1.00)
they will equal the mixture desired 60% juice, or 0.60, namely (4+x)(0.60)
thus (4)(0.50) + (x)(1.00) = (4+x)(0.60)
solve for "x"
