Solution

To find the equation of the line in the form y = mx + c, we first need to find the slope (m) and the y-intercept (c).

Step 1: Find the slope (m) The slope of a line is the change in y divided by the change in x. From the table, we can take two points to calculate this. Let's take the points (0, -3) and (2, 1).

m = (y2 - y1) / (x2 - x1) m = (1 - (-3)) / (2 - 0) m = 4 / 2 m = 2

Step 2: Find the y-intercept (c) The y-intercept is the value of y when x = 0. From the table, we can see that when x = 0, y = -3. So, c = -3.

Therefore, the equation of the line is y = 2x - 3.
