  1. Wednesday November 20, 2013Bell Ringer: Find the x and y intercepts for the following equation: 2y + 6x = 24

  2. What We are Learning Today: • To determine if a given Ordered Pair is a solution to an equation • To find solutions of an equation

  3. Checking an Ordered Pair: • REMEMBER: in an ordered pair the x ALWAYS is first, the y is second • (x, y) • Replace the x with the x value from the ordered pair • Replace the y with the y value from the ordered pair • Simplify both sides • Are the two sides equal? • YES? This is a solution • NO? This is NOT a solution

  4. Let’s Try These Together: y = 2x – 4; (7, 10) y = -½x + 12; (10, 5)

  5. Finding Solutions for an Equation: • Draw a table • Choose values for x and put it in the table • -1, 0, 1, 2 are usually good choices • Put these values into the equation for x • Solve the equation for y (y = a number) • These are the solutions for your equation • Write them as an Ordered Pair • Hint: • If the slope is a fraction choose numbers that are multiples of the denominator

  6. Let’s Try This: • Find three solutions for y = 3x + 5

  7. Practice Time! • Workbook • Page 151 • 1-6 • Show ALL of your work for credit • NO work = NO credit!!!!! • This is your Task for the week! • You will be quizzed on this on Friday!
