Lesson 5.3- Slope Intercept Form, pg. 272Goals: To write and graph linear equations in slope-intercept form. To model real-world data with an equation in slope-intercept form.
Slope-Intercept Form The linear equation y = mx + b is written in slope-intercept form, where m is the slope and b is the y-intercept. Y = mx + b slope Y-intercept
Ex. 1: Write an equation given slope and y-intercept
slope: 0.5 y-intercept: 7.5 slope: 8 y-intercept: -3 slope: 4 y-intercept: -2 slope: -1 y-intercept: -7
Ex. 2: Write an equation of the line shown in each graph.1. y x 5 -5
2. y x 5 -5
3. y x 5 -5
Ex. 3: Graph the equation. 1. y = x - 2 y x 5 -5
2. y = -x + 2 y x 5 -5
3. y = -1/3x - 3 y x 5 -5
4. 2x – y = -3 y x 5 -5
5. 4x – 3y = 3 y x 5 -5
Ex. 3: Write a linear equation in slope-intercept form to model the situation.An auto repair shop charges $50 plus $25 per hour. Y = mx + b
2. The temperature is 15° and is expected to fall 2° each hour during the night.Y = mx + b
A computer technician charges $75 for a consultation plus $35 per hour.Y = mx + b
Objective - To graph linear equations using the slope and y-intercept.
One method of graphing a linear equation is to construct a table of values. Example: Consider the equation y = 2x + 3 xy When x = 0, y =
WARM UP 1. Explain how to graph a linear equation written in slope-intercept form. 2. Explain how to graph a linear equation written in point-slope form.

Chapter 5 Review.
2.4 Writing the Equation of a Line
Unit 1 Solving Linear Systems by Graphing
The table and graph suggest another method of graphing a linear equation. This method is based on two numbers. The SLOPE This is the coefficient of x.
4.2 Graphing Linear Equations
Warm Up Graph each equation on the same coordinate plane and describe the slope of each (zero or undefined). y = 2 x = -3 y = -3 x = 2.
Y = 1 2 x y = 1 2 x - 1 What happens if we graph a system of equations and the lines are parallel?
Warm up Graph the equation of the line using slope & y-intercept
Graph a linear equation Graph: 2x – 3y = -12 Solve for y so the equation looks like y = mx + b - 3y = -2x – 12 Subtract 2x to both sides. y = x + 4 Divide.
