1. Lesson 3-6: More Equations of Lines
Objective
Students will:
Write equations given two points
State the slope and y-intercept from an equation
Graph linear equations
Find the standard form of equations

2. Example 1: Find the slope and y-intercept of y = 6x + 9
b=???? (0, ?)
This should be an easy one!!!

3. Example 2: Find the slope and y-intercept of 6x + 2y = 24
Hint: Solve for y, then like Ex 1
m=????
b= ????? (0,?)
Remember equations like Ax + By =C are called standard form.
(no fractions and A is positive)
The slope is given as m = Why????

4. Example 3: Write 2x + 8 = 5y in standard form

5. Example 4: Write the equation of the line through (3,1) and (5, 7)
2 choices
a) point-slope or b) slope intercept
Both require SLOPE!!!!!! Which we do not have!!!!
Find the slope m= ???
then complete using a) and b) from yesterday’s notes
(Make sure to pick only one point to substitute –doesn’t matter which can be same one in both methods)
a) b)
