Objective: Students will be able to graph a line using a table that they create. Students will be able to test a given value to decide if it is a solution.
1. Be sure that p 219 #11­22 is on your desk.
2. Do the warm­up problems.
3. Check on your teammates. Ask for help if needed, offer help if needed.
4. Once the entire team has the same answers to the warm­ups please sit quietly.
Warm ­Ups
Solve each equation for y.
2x ­ 4y = 16
­3x + 7y = 14
3x ­ y = 10
Making a table of values that work.
Decide if each point is on the line.
2x + 4y = 8
a. (8, ­6)
b. (6, ­1)
c. (1, 3/2)

Graphing lines using the x­intercepts and y­intercepts.
This is a short cut
so you do not have
to make a large chart. Examples: Find the x and y intercepts and graph each equation.
1. 2x + 7y = 28
To find the x­
intercept, put 0 in for y.
To find the y­
intercept, put 0 in for x.
2. x + 2y = 4
3. 4x + 0.5y = 8
4. y = 4x ­ 2
