Math Problem Statement

Write a linear equation for the line with a slope of -8 and a y-intercept of -3.

Solution

The question asks us to write a linear equation for a line with a slope of 8-8 and a y-intercept of 3-3.

Solution:

The general form of a linear equation in slope-intercept form is:

y=mx+by = mx + b Where:

  • mm is the slope.
  • bb is the y-intercept.

Given:

  • m=8m = -8
  • b=3b = -3

Substitute these values into the equation:

y=8x3y = -8x - 3

Final Answer:

The linear equation is:

y=8x3y = -8x - 3
