Math Problem Statement

Which point is NOT on the line y = 2x - 3?

Solution

To determine which point is not on the line y=2x3y = 2x - 3, we need to check each point by plugging its xx-value into the equation and seeing if the corresponding yy-value matches.

Given points:

  1. (2,2)(2, 2)
  2. (1,1)(1, -1)
  3. (0,3)(0, -3)
  4. (3,3)(3, 3)

Let's test each one:

  1. For (2,2)(2, 2): y=2x3=2(2)3=43=12y = 2x - 3 = 2(2) - 3 = 4 - 3 = 1 \neq 2 So, (2,2)(2, 2) is not on the line.

Since the first option does not satisfy the equation, we have already found the point that is not on the line.

Answer:

The point that is not on the line y=2x3y = 2x - 3 is (2,2)(2, 2).

Would you like a detailed explanation of how I would test the other points or have any questions?

Tip:

For any line equation y=mx+by = mx + b, plug in the xx-value of a point into the equation to see if the resulting yy-value matches the point’s yy-coordinate.
