Graph a system of equations in slope-intercept or standard form, and find their solution using the graphs.

Problem

The following two equations form a linear system.
space, 5, x, minus, 10, y, equals, 20
space, 2, x, plus, 4, y, equals, minus, 16
Graph both equations.
What is the solution to the system?
  • x, equals
    • Your answer should be
    • an integer, like 6
    • a simplified proper fraction, like 3, slash, 5
    • a simplified improper fraction, like 7, slash, 4
    • a mixed number, like 1, space, 3, slash, 4
    • an exact decimal, like 0, point, 75
    • a multiple of pi, like 12, space, p, i or 2, slash, 3, space, p, i
  • y, equals
    • Your answer should be
    • an integer, like 6
    • a simplified proper fraction, like 3, slash, 5
    • a simplified improper fraction, like 7, slash, 4
    • a mixed number, like 1, space, 3, slash, 4
    • an exact decimal, like 0, point, 75
    • a multiple of pi, like 12, space, p, i or 2, slash, 3, space, p, i
