A girl went to a shop to buy pineapples and apples. A pineapple cost $2 more than an apple. The girl bought as many pineapples for $60 as she bought apples for $54. How much does a pineapple and an apple cost together?

Iwould think that the correct answer is 8.1

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!
