From the graph, the solution of the two system of equations is (-0.571, -3.286).
How to solve the linear equation using graph?
The solution of the two system of equations can be obtained using graphing calculator as shown below.
The given system of equations;
y = -3x - 5
y = -10x - 9
To plot the graph, we can choose random values of x and calculate the corresponding values of y.
For example, when x = 0, the value of y is calculated as;
y(0) = 0 - 5 = - 5
y(0) = 0 - 9 = -9
when x = 1, the value of y is calculated as;
y(1) = -3(1) - 5 = - 8
y(1) = -10(1) - 9 = - 19
Thus, from the graph, the solution of the two system of equations = (-0.571, -3.286)
