Rewrite the equation in slope intercept form, identify the slope and y-intercept, and select the correct graph.

2x - 5y = 10

1 answer

To rewrite the equation \(2x - 5y = 10\) in slope-intercept form (\(y = mx + b\)), we need to solve for \(y\).

  1. Start with the original equation: \[ 2x - 5y = 10 \]

  2. Subtract \(2x\) from both sides: \[ -5y = -2x + 10 \]

  3. Divide each term by \(-5\): \[ y = \frac{2}{5}x - 2 \]

Now, the equation is in the slope-intercept form \(y = mx + b\), where:

  • \(m\) (the slope) is \(\frac{2}{5}\)
  • \(b\) (the y-intercept) is \(-2\)

So, the slope is \(\frac{2}{5}\) and the y-intercept is \(-2\).

To select the correct graph, look for:

  1. A line with a slope that rises \(2\) units for every \(5\) units it moves to the right.
  2. The line crossing the y-axis at \(-2\).

This information should help you identify the correct graph corresponding to the equation.
