Math Problem Statement

for equation y=-3x+2 calculate the slope and y intercept

Solution

The given equation is:

y=3x+2y = -3x + 2

This is a linear equation in the slope-intercept form, which is:

y=mx+by = mx + b

where:

  • mm is the slope of the line.
  • bb is the y-intercept, the point where the line crosses the y-axis.

1. Slope

In the equation y=3x+2y = -3x + 2, the coefficient of xx is 3-3. Therefore, the slope (mm) is:

slope=m=3\text{slope} = m = -3

2. Y-Intercept

The y-intercept (bb) is the constant term in the equation. In this case, it is 22. Therefore, the y-intercept is:

y-intercept=b=2\text{y-intercept} = b = 2

Summary

  • Slope (mm): 3-3
  • Y-Intercept (bb): 22
