Answer and Step-by-step explanation:
To find the unit rate of change (slope), we have to use the formula to find the slope, and it is as follows:
[tex]\frac{y_{2}- y_1}{x_{2}- x_1}}[/tex]
Input Batch 2 and 1 into the formula (Batch 2 being the y2 and x2, and Batch 1 being y1 and x1).
[tex]\frac{6.75-2.25}{3-1} = 2.25[/tex]
2.25 is our slope.
The equation for the line would be y = 2.25x
To check the answer, plug in 4 (from Batch 3), and if it equals the number of cups of flour, then the answer is correct.
2.25(4) = 9 ✔️
The graph is below.
I hope this helps!
