Math Problem Statement

Decide which of the ordered pairs are solutions for the equation y = 4x + 2.

Solution

The equation given in the problem is:

y=4x+2y = 4x + 2

We need to check which of the ordered pairs (2,6)(-2, -6), (1,0)(-1, 0), (2,6)(-2, 6), and (0,2)(0, 2) satisfy this equation.

1. For (2,6)(-2, -6):

Substitute x=2x = -2 into the equation: y=4(2)+2=8+2=6y = 4(-2) + 2 = -8 + 2 = -6 Since the calculated y=6y = -6 matches the given y=6y = -6, this pair is a solution.

2. For (1,0)(-1, 0):

Substitute x=1x = -1 into the equation: y=4(1)+2=4+2=2y = 4(-1) + 2 = -4 + 2 = -2 Since the calculated y=2y = -2 does not match the given y=0y = 0, this pair is not a solution.

3. For (2,6)(-2, 6):

Substitute x=2x = -2 into the equation: y=4(2)+2=8+2=6y = 4(-2) + 2 = -8 + 2 = -6 Since the calculated y=6y = -6 does not match the given y=6y = 6, this pair is not a solution.

4. For (0,2)(0, 2):

Substitute x=0x = 0 into the equation: y=4(0)+2=0+2=2y = 4(0) + 2 = 0 + 2 = 2 Since the calculated y=2y = 2 matches the given y=2y = 2, this pair is a solution.

Final Answer:

  • (2,6)(-2, -6) is a solution.
  • (1,0)(-1, 0) is not a solution.
  • (2,6)(-2, 6) is not a solution.
  • (0,2)(0, 2) is a solution.

  2. What happens if we change the slope in the equation y=4x+2y = 4x + 2?
  3. How do we graph linear equations like y=4x+2y = 4x + 2?
  4. What is the effect of changing the constant in the equation y=4x+2y = 4x + 2?
  5. Can there be no solution for some ordered pairs for a linear equation?

Tip: When solving linear equations with ordered pairs, always check by substituting both the xx- and yy-values into the equation.
