To answer this question, we need to identify two points on the graph. These points are:

(4, 7) and (0, -9). These points are easy to identify, and a line is defined by two points.

We are going to use the two-point equation of the line to finally find the slope-intercept form of the line.

The formula to find the line is:


y-y_1=(y_2-y_1)/(x_2-x_1)(x-x_1)

We have two points, and we need to label them as follows:

(4, 7) ---> x1 = 4, y1 = 7

(0, -9) ---> x2 = 0, y2 = -9

Then, we have:


y-7=(-9-7)/(0-4)(x-4)\Rightarrow y-7=(-16)/(-4)(x-4)\Rightarrow y-7=4(x-4)

Then, we have:


y-7=4x-16\Rightarrow y=4x-16+7\Rightarrow y=4x-9

Therefore, the equation of the line is equal to:


y=4x-9

We need to write:

• In the first box ---> ,4

,

• In the second box --->, -9
