Explanation:
a. Using two pairs of values given, (0, 12) and (1, 18)
Rate/slope =
![m = (y_2 - y_1)/(x_2 - x_1) = (18 - 12)/(1 - 0) = (6)/(1) = 6](https://img.qammunity.org/2021/formulas/mathematics/college/7919i6wbzo5usbl1yznzkfa3qy6swwyky9.png)
Unit rate/slope (m) = 6
b. The starting value is the y-intercept (b). It is the value of of y when x = 0.
From the table, when x = 0, y = 12.
Therefore the starting value (b) would be 12.
c. The equation can be written in slope-intercept form,
, where,
m = slope/rate = 6
b = starting value/intercept = 12.
Plug in the values into the equation
The equation would be:
