1. 3.7 Equations of Lines in the Coordinate Plane
By Brit Caswell

2. Student Objectives and EQ
Students will graph and write linear equations.
How do certain facts such as slope and a point on the line help to determine the graph of an equation?

3. A little review…

4. The four types of slope

5. Find the slopes of these lines

6. We will look at two types of equation layouts
We will look at two types of equation layouts.. The slope-intercept form And the point-slope form

7. Graph y = x + 1

8. Graph y – 3 = -2(x + 3)

9. Pg 192, #3
What is the equation of a line with slope 3 and y-intercept at -5? What is the equation of a line through (-1, 5) with a slope of 2?

10. Write an equation for this line

11. Write an equation for the lines
