Question

finding the coordinates of a point on a graph given the equation. the graph of the equation y = 0.7x - 3 is shown below. point k is on the graph. what are the coordinates of k?

Explanation:

Step1: Observe the x - coordinate of point K

From the graph, the x - coordinate of point K is 3.

Step2: Calculate the y - coordinate

Substitute x = 3 into the equation y = 0.7x−3. So y=0.7×3 - 3=2.1 - 3=- 0.9.

Answer:

(3, - 0.9)
