Question

Solve the system by graphing. Y= -2x +3.y= -x - 1

Answer 1

To solve the system by graphing, plot the equations on a coordinate plane and find the point of intersection.

Step-by-step explanation:

To solve the system by graphing, we need to plot the equations on a coordinate plane and find the point of intersection, which represents the solution to the system.

For the first equation, y = -2x + 3, we can start by plotting the y-intercept at (0, 3) and then using the slope of -2 (rise of -2, run of 1) to find additional points.

Similarly, for the second equation, y = -x - 1, we can start by plotting the y-intercept at (0, -1) and then using the slope of -1 (rise of -1, run of 1) to find additional points.

Answer 2

Solve by graphing:
3x-y = 1
3x-y = 2
To graph, rewrite these eqautions as:
y = 3x-1
y = 3x-2
Notice that the lines have the same slope of m = 3 so you know that the lines are parallel,therefore, there is no solution.
