Question

Help please I don’t understand

Answer 1

The answer is:

(1, -2)

Work/explanation:

This system has been solved by the graphing method; both equations have been graphed, and to find the solution, I need to find the point where both graphs intersect. And the graphs are the lines.

The x co-ordinate of the point is the solution for x, and the y co-ordinate of the point is the solution for y.

In our case, the lines intersect at (1, -2), which means that the value of x is 1, and the value of y is -2.

Answer 2

(1, -2)

Systems of Equations

The solution to a system of equations is the point where the 2 lines intersect.

Q)

Examine the graph. Where do the 2 lines intersect?

(1,-2)
