Question

solving systems of equation by graping practice

Answer 1

To practice solving systems of equations by graphing, you can follow these steps:

1. Choose a system of equations to solve. For example, consider the following system of equations:
- Equation 1: y = 2x + 3
- Equation 2: y = -x + 5

2. Plot the equations on a graph. To do this, first identify the y-intercepts of each equation by setting x = 0 and solving for y. Then, identify the x-intercepts by setting y = 0 and solving for x. Plot these points on the graph and draw a line through them.

3. In this case, the y-intercepts are (0, 3) for Equation 1 and (0, 5) for Equation 2. The x-intercepts are (-1.5, 0) for Equation 1 and (5, 0) for Equation 2. Plot these points on the graph and draw the lines.

4. Determine the point of intersection between the two lines. This point represents the solution to the system of equations.

5. In this case, the point of intersection is (2, 7). Therefore, the solution to the system of equations is x = 2 and y = 7.

By practicing this method with different systems of equations, you can improve your graphing skills and successfully solve systems of equations.
