Math Problem Statement

Graph the equation y = -5x + 3.

Solution

The equation shown is y=5x+3y = -5x + 3, which represents a linear equation in slope-intercept form:

y=mx+by = mx + b

Where:

  • m=5m = -5 is the slope (rate of change).
  • b=3b = 3 is the yy-intercept (where the line crosses the yy-axis).

Key Observations:

  1. Slope (m=5m = -5):

    • A negative slope means the line is decreasing.
    • For every 11 unit increase in xx, yy decreases by 55 units.
  2. Y-Intercept (b=3b = 3):

    • The line crosses the yy-axis at (0,3)(0, 3).

How to Graph:

  1. Plot the yy-intercept at (0,3)(0, 3).
  2. Use the slope:
    • Move down 55 units (negative slope).
    • Move right 11 unit (positive direction for xx).
    • Plot the next point.
  3. Draw a straight line through these points.

Here are 5 related questions to deepen your understanding:

  1. What is the slope of a line parallel to y=5x+3y = -5x + 3?
  2. What is the slope of a line perpendicular to y=5x+3y = -5x + 3?
  3. How do you find the xx-intercept of the equation y=5x+3y = -5x + 3?
  4. What happens to the graph if the slope changes to 2-2 but the yy-intercept stays 33?
  5. How do you rewrite y=5x+3y = -5x + 3 in standard form Ax+By=CAx + By = C?

Tip:

When graphing a line, always start with the yy-intercept and use the slope (rise/run) to plot additional points.
