Explanation:
Let x represent number of servings and y represent calories.
We have been given a table of values for calories from different servings of fruit (in cups).
We are supposed to graph the given information.
Points on the line would be (1,70), (3,210) and (5,350).
First of all, we will find slope as:
![m=(210-70)/(3-1)](https://img.qammunity.org/2020/formulas/mathematics/middle-school/kvylptqx8i5td1ub9qu3cy495khq0dovju.png)
![m=(140)/(2)](https://img.qammunity.org/2020/formulas/mathematics/middle-school/oe3v5uo3wvjsjaft7rh2a369q6cebmr42l.png)
![m=70](https://img.qammunity.org/2020/formulas/mathematics/middle-school/g1ypmrdm3ecvs4zaggbt6w37497jngpr1f.png)
Upon substituting
and coordinates of point (1,70) in point-slope form, we will get:
![y-70=70(x-1)](https://img.qammunity.org/2020/formulas/mathematics/middle-school/xpex2lnabei7ak6sel0cq87qihmqks2atz.png)
![y-70=70x-70](https://img.qammunity.org/2020/formulas/mathematics/middle-school/66bbal6xy1tx2vmfq7k0mjxflt1e5j7y3d.png)
![y-70+70=70x-70+70](https://img.qammunity.org/2020/formulas/mathematics/middle-school/yfkbfj470djjmvxhf32r750qejavu9d9ki.png)
![y=70x](https://img.qammunity.org/2020/formulas/mathematics/middle-school/kqa7l0vujw175v4bg0616s41a3g83te34x.png)
Upon graphing our equation, we will get our required graph as shown in the attachment.
