look at this graph: what is the equation of the line in point - slope form? use the red point in your…

Explanation:

Step1: Find the slope

Let's assume two points on the line. From the graph, if we take two visible points (let's say the red - point and another identifiable point). Suppose the red - point is ((x_1,y_1)=(200,600)) and another point on the line could be ((0,400)). The slope (m=\frac{y_2 - y_1}{x_2 - x_1}=\frac{600 - 400}{200-0}=\frac{200}{200}=1).

Step2: Write the point - slope form

The point - slope form of a line is (y - y_1=m(x - x_1)). Using the red point ((x_1,y_1)=(200,600)) and (m = 1), we get (y-600=1(x - 200)).

Answer:

(y - 600=1(x - 200))
