Solving equations HW on K. A.

Log in to Khan Academy first! 

then click on each of the links and get 10 correct answers for each link (Substitution, Elimination, and Graphing). Should be a total of 30 correct problems. 

1. Systems of Equations

1. Practice solving by substitution on Khan Academy.

1. https://www.khanacademy.org/math/cc-eighth-grade-math/cc-8th-systems-topic/cc-8th-systems-with-substitution/e/systems_of_equations_with_substitution

2. Practice Solve by elimination or substitution…

1. https://www.khanacademy.org/math/algebra/systems-of-eq-and-ineq/fast-systems-of-equations/e/systems_of_equations

3. Practice solve by graphing in Khan Academy. - System of Linear Equations.

1. In the following link they'll give you two equations.

2. Use your own paper to find the points where the line should go (using the y-intercept and slope, or using the x-intercept and y-intercept).

3. Once you know where the points should be, use the mouse and drag each line to where it's supposed to be and check your answers. Great way to practice.

4. https://www.khanacademy.org/math/algebra/systems-of-eq-and-ineq/fast-systems-of-equations/e/graphing_systems_of_equations

4. special cases of systems of equations.

1. Infinite solutions and No Solutions.

Khan Academy bonus + joint my class.

If you have not done so, please join my Khan Academy Alg1 class. 

The code to be in my class/coach is QYNXQX  . Go to "add coach" paste this code. Most of you have done this in the begging of the year already...

Below is a link for you to practice Graphing and solving systems of equations. Be sure to log in to Khan Acad. first (on a new tab), then click on the link below... 

1. Practice graphing in Khan Academy. - System of Linear Equations.

1. In the following link they'll give you two equations.

2. Use your own paper to find the points where the line should go (using the y-intercept and slope, or using the x-intercept and y-intercept).
