Math Problem Statement

Give the slope and the y-intercept of the line with the given equation. Then, graph the linear equation: y = (-3/8)x.

Solution

The equation given in the image is:

y=38xy = \frac{-3}{8}x

This equation is in the slope-intercept form:

y=mx+by = mx + b

Where:

  • mm is the slope of the line.
  • bb is the y-intercept.

Step 1: Identify the slope

In this case, m=38m = \frac{-3}{8}, so the slope is:

slope=38\text{slope} = -\frac{3}{8}

Step 2: Identify the y-intercept

There is no constant term, which means the y-intercept b=0b = 0. So, the line passes through the origin (0,0)(0, 0).

Final Answer:

  • The slope is 38-\frac{3}{8}.
