Accepted Solution
A:
1. Eyeballing the data, the best fit will be pretty close to a line between the leftmost point and the rightmost point.We estimate those points as (4,220) and (28,470)The point point form for a line joining (a,b) and (c,d) is(c-a)(y-b) = (d-b)(x-a)(28 - 4)(y - 220) = (470 - 220)(x - 4)24(y - 220) = 250(x-4)24y - 5280 = 250x - 100024y = 250 x + 4280y = (250/24) x+ (4280/24)Approximately that's,y = 10.4 x + 178Answer: 4th choice, 10.4x + 1802. For 48 wheelbarrows,y = 10.4(48)+180 = 679.2Answer: 679.2 liters of sand
