Math Problem Statement

Find the x- and y-intercepts. Write ordered pairs representing the points where the line crosses the axes for the equation y = -2x.

Solution

Let's solve this problem step by step. The given equation is:

y=2xy = -2x

1. Finding the y-intercept:

The y-intercept occurs when x=0x = 0. Substituting x=0x = 0 into the equation:

y=2(0)=0y = -2(0) = 0

Thus, the y-intercept is (0,0)(0, 0).

2. Finding the x-intercept:

The x-intercept occurs when y=0y = 0. Substituting y=0y = 0 into the equation:

0=2x0 = -2x

Solving for xx:

x=0x = 0

Thus, the x-intercept is (0,0)(0, 0).

Conclusion:

Both the x-intercept and y-intercept are (0,0)(0, 0). So, you can fill in the boxes as follows:

  • The x-intercept is (0,0)(0, 0).
  • The y-intercept is (0,0)(0, 0).
