9. y intercept 3; m = -\\frac{2}{5}

Question

  1. y intercept 3; m = -\frac{2}{5}

Explanation:

Identify the given information

We are given:

  • The \(y\)-intercept: \((0, 3)\)
  • The slope: \(m = -\frac{2}{5}\)

Plot the y-intercept

Using the Graphing Linear Equations knowledge point

$$ \text{Plot the point } (0, 3) \text{ on the } y\text{-axis.} $$

Find a second point using the slope

Using the Graphing Linear Equations knowledge point

$$ LATEXBLOCK0 $$

Draw the line

Using the Graphing Linear Equations knowledge point

$$ \text{Draw a straight line passing through } (0, 3) \text{ and } (5, 1). $$

Answer:

To graph the line:

  1. Plot the \(y\)-intercept at \((0, 3)\).
  2. Use the slope \(m = -\frac{2}{5}\) (rise of \(-2\), run of \(5\)) to find a second point at \((5, 1)\).
  3. Draw a straight line through both points.
