general form of a linear equation
Sketch the graph of 3x + 2y = 18.
Determine where the lines intersect.
2x + 5y = 103x + 4y = 12
When two linear equations have no common solution, their graph
are ???
When two linear equations have infinitely many solutions, their
graph are ???
Solve. Then graph the solutions.
3x - y = 97x - 5y = 25
Distance Formula:
Midpoint Formula:
If A = (-1, 9) and B = (4, -3), find the length of AB and the
coordinates of the midpoint of AB.
