1. Lesson 5.1 – 5.2 Write Linear Equations in Slope-Intercept Form
Essential Question: How do you write an equation of a line in slope-intercept form? How do you write an equation given two points?

2. Before we start… What is a y-intercept? Where is it on a graph?
If you look at a coordinate point, how can you tell if it is a y-intercept?

3. What is Slope-Intercept Form?
Recall the graph of this equation is a line with a slope of m and a y-intercept of b.

8. How do you write an equation given the slope and a point on the line?
Identify the slope m.
Start in point-slope form.
Convert the equation to slope-intercept by solving for y.
Verify the equation is in slope-intercept form
y = mx + b

13. How do you write an equation of a line given two points?
Calculate the slope.
Plug into point-slope form.
Use the slope and a point given.
Write the equation.
y = mx + b

18. How do you write a linear function?
Write the function notation as ordered pairs
Calculate the slope
Find the y-intercept
Use the slope and a given point
Write the equation
f (x) = mx + b
