Associated sells oranges at 3.00 for five pounds and apples at 3.99 for three pounds. shoprite sells oranges at 2.59 for four pounds and apples at 1.98. which store has the better buy for oranges?

3.00/5 = 0.6 = 60p per pound
2.59/4 = 0.6475 = 64/5p per pound

Therefore the first shop is better for money with being 4p cheaper

Hope this helped :)

Abit confused about what you mean, but i think you might be referring to slope intercept form: y = mx + bin that case b, or the y intercept is already given.(0,-1)find the slope by using the formulay2 - y1/x2 - x1the final slope will be 4/2, equivalent to 2.now your equation should look like thisy = 4/2x -1sorry if this didn’t you out!
