Math Problem Statement

Find the slope and y-intercept of the line -2x + y = -4.

Solution

The equation provided in the image is:

2x+y=4-2x + y = -4

To find the slope and the y-intercept, we need to rewrite the equation in slope-intercept form, y=mx+by = mx + b, where mm is the slope and bb is the y-intercept.

  1. Solve for yy:

y=2x4y = 2x - 4

Now, we can identify:

  • The slope mm is 22.
  • The y-intercept bb is 4-4.

Thus, the slope is 22, and the y-intercept is 4-4.

Would you like a detailed explanation of how to graph this line, or do you have any questions?

Here are 5 related questions for deeper exploration:

  1. What is the significance of the slope in the graph of a line?
  2. How do you determine the x-intercept of a line from its equation?
  3. How does changing the slope affect the steepness of a line?
  4. How can you graph a line using only the slope and y-intercept?
  5. What happens to the graph of a line when the y-intercept changes?

Tip: When graphing a line, start by plotting the y-intercept, then use the slope to find another point on the line.
