Acute, right, obtuse, and straight angles
Acute, right, obtuse, and straight angles
What you'll learn
- Determine whether a given ordered pair (x, y) is a solution to a system of two linear equations by substituting the values of x and y into each equation and verifying that both equations are satisfied.
- Identify, given a system of two equations (linear or non-linear) and a set of ordered pairs, all the ordered pairs that satisfy the system by substituting the x and y values into each equation.
- Explain why a given ordered pair (x, y) is or is not a solution to a system of equations, justifying their reasoning based on the results of the substitution process.
- Solve systems of two equations for x and y by graphing and demonstrate that the solution is the point of intersection.
