Write an equation that can determine the cost for any number of pounds of strawberries purchased. (6,15)
(2,5)
(1,2.5)

y=2.5x

Step-by-step explanation:

To get the equation in y = mx + b format, we need to find m and b, the slope and y-intercept.

To find the slope, we need two points on a graph, which we have.

First, the slope

The formula for slope is

Our points, (6, 15) and (2, 5)

Plugging into our equation:

, which is 10 divided by 4, which is 2.5

Our equation now:

To find our b, we need to plug in one x value.

(6, 15) are our pair of points.

6 = x

15 = y

=> =>

If b is 0, then we don't need to include b.

Our equation is

i you goofed up when writing this, because hnot is not a word minusf is not either. i cannot answer   because of that.

step-by-step explanation:

you probably already have the answer but anyways it's b. 15.0
