ANSWER:

Explanation:
We have a linear equation has the following form:

We must identify the coordinates of the yellow points in order to calculate the slope value, the points are (0, 6) and (7, 2). We calculate the slope as follows:

Now, the value of b we see explicitly in the graph because the y-intercept is (0.6), therefore the value of b is 6, the equation would be:
