Algebra Standard 7.0

 

 

Definition: Students verify that a point lies on a line given by an equation of the line. Students are also able to derive linear equations by using the point-slope formula.

 

Student friendly: Students can make sure a point is on a line when the equation is given. Students also come up with linear equations with point-slope form.

 

 

What is Point-Slope Form? 

 

 

 

You are given the point (-3,-2) and a slope of 2.

 

 

1. Plug what you have into the Point-Slope Formula     ---->       y-(2)=2[x-(-3)]

 

2. Distribute the 2 to the x and -3                                    ---->        y-2=2x+6

 

3. Add 2 to both sides                                                      ---->        y=2x+8

 

 

 

 

 

What is Standard Form?

 

Ax+By=C

 

 

Now we have to put the equation into Standard Form

 

1. Subract 2x from both sides                                           ---->        -2x+y=8
