Question

finding the coordinates of a point on a graph given the equation. graph of the equation y = 0.4x - 4 is shown below. point a is on the graph. what are the coordina

Explanation:

Step1: Observe the x - value of point A

By looking at the graph, the x - value of point A is 5.

Step2: Substitute x into the equation

Substitute \(x = 5\) into \(y=0.4x - 4\). So \(y=0.4\times5-4\).

Step3: Calculate y - value

First, \(0.4\times5 = 2\), then \(y=2 - 4=-2\).

Answer:

\((5,-2)\)
