Math Problem Statement

What is the equation of the line passing through the points on the graph?

Solution

Based on the visual inspection of the graph, the line passes through two distinct points:

  • Point 1: (5,2)(-5, -2)
  • Point 2: (1,1)(1, 1)

Next, we will calculate the slope mm using the formula: m=y2y1x2x1m = \frac{y_2 - y_1}{x_2 - x_1} After determining the slope, we will use one of the points to find the equation of the line.The slope of the line is m=0.5m = 0.5.

Now, using the point-slope form of a line equation with one of the points, say (5,2)(-5, -2), we can write:

y(2)=0.5(x(5))y - (-2) = 0.5(x - (-5))

Let's simplify this equation to get it into slope-intercept form y=mx+by = mx + b.The y-intercept bb is 0.5. Therefore, the equation of the line in slope-intercept form is:

y=0.5x+0.5y = 0.5x + 0.5

This is the equation of the line passing through the points (5,2)(-5, -2) and (1,1)(1, 1).
