Writing Linear Equations in Slope-Intercept Form

5.1

y = mx + b

  • How to find the Equation of a Line:

  • Find the slope (m) of the line.

  • Find the y-intercept (b) of the line.

  • Plug these values into y = mx + b

Writing Linear Equations in Slope-Intercept Form

5.2

y = mx + b

  • How to find the Equation of a Line:

  • Find the slope (m) of the line.

  • Find the y-intercept (b) of the line.

    • Plug m and a point into the equation

  • Plug these values into y = mx + b

Example 1

Writing an Equation of a Line

Write the equation of the line whose slope m = -2 and passes through the point (6, -3).

Find the equations of the lines:

y = -2x + 9

Example 3

Writing an Equation of Parallel Lines

Write the equation of the line that is parallel to the line y = -3x – 2 and passes through the point (3, -4)

Find the equations of the lines:

y = -3x + 5

Example 4

Real Life Linear Models

Between 1995 and 2005, the number of vacation trips in the U.S. take by U.S. residents increased by about 26 million per year. In 2003, U.S. residents went on 740 million vacation trips. Write linear equation the models the number of vacation trips, y (in millions), in terms of the year, t. Let t be the number of years from 1995.

Estimate the number of trips in 2015.

y = 26t + 532

≈ 1052 million trips

Example 4

Real Life Linear Models

All the employees of a garden center are given a $.40 per hour raise each year. You make $7.15 per hour after three years as an employee. Write a linear equation that models your salary per hour S in terms of n the number of years you have worked at the garden center. Then find your hourly salary after 6 years.

S = .4n + 5.95

$8.35/hr
