Math Problem Statement

Solve this

Write an equation in slope-intercept form for the line with y-intercept 8 and slope -8.

Solution

To solve the problem in the image:

We are asked to write the equation of a line in slope-intercept form y=mx+by = mx + b, where:

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

Given:

  • m=8m = -8 (slope)
  • b=8b = 8 (y-intercept)

Substitute:

The equation becomes: y=8x+8y = -8x + 8

This is the equation of the line in slope-intercept form.
