Math Problem Statement

What is the graph of the equation y = -1/4x + 2?

Solution

The question is about the equation y=14x+2y = -\frac{1}{4}x + 2.

  1. Y-intercept: The equation is in slope-intercept form, y=mx+by = mx + b, where mm is the slope, and bb is the y-intercept. Here, the y-intercept is 22, which means the line crosses the y-axis at the point (0,2)(0, 2).

  2. Slope: The slope mm is 14-\frac{1}{4}. Since it is negative, the line will slope downward from left to right.

Therefore, the answer to the last part:

  • The line goes downward from left to right.

Here are some related questions to explore:

  1. How do you determine the direction of a line based on its slope?
  2. What does the y-intercept represent in a real-world context?
  3. How can you find the x-intercept of the equation y=14x+2y = -\frac{1}{4}x + 2?
  4. How would the graph change if the slope were positive?
  5. What is the effect of changing the y-intercept in the equation?

Tip: In slope-intercept form, the slope tells you the direction and steepness of the line, while the y-intercept indicates where the line crosses the y-axis.
