1. Do Now
Rewrite the equation 6x - 2y = 8 in slope intercept form. (y = mx + b)
What is the equation in slope intercept form?
What number represents the slope?
What does the slope mean?

2. Do Now 6x - 2y = 8 -6x -6x - 2y = -6x + 8 - 2 -2 -2 y = 3x - 4
Rewrite the equation 6x - 2y = 8 in slope intercept form. (y = mx + b)
What is the equation in slope intercept form?
6x - 2y = 8
-6x x
- 2y = -6x + 8
y = 3x - 4

3. Do Now
Rewrite the equation 6x - 2y = 8 in slope intercept form. (y = mx + b)
What number represents the slope?
What does the slope mean?
y = 3x - 4
The slope is 3
The slope means 3 up and 1 to the right

4. Writing the equation of a line
Write an equation of the line given 2 points
SWBAT:

5. Equations of a line
Yesterday, we learned how to use the point slope form of a line
To use this equation you must have a point (x, y) and a slope (m)

6. Equations of a line
Let’s look at this situation. You have two points, (-6,-3) and (3 , 0). If you graphed both points you would get the following line

7. Equations of a line
Write the equation of a line that passes through the points (-6,-3) and (3 , 0).
If I wanted to use this formula, I would need to have a point and a slope.
So what am I missing?

8. So let’s find the slope between the points
Equations of a line
So let’s find the slope between the points
(-6,-3) and (3 , 0).

9. Equations of a line
So now we know that the slope is 1/3 we can write the equation of a line that passes through the points (-6,-3) and (3 , 0).

10. Equations of a line
So now we know that the slope is 1/3 we can write the equation of a line that passes through the points (-6,-3) and (3 , 0).
