Answer:
(6, -4)
Step-by-step explanation:
To solve a linear system of equations <u>graphically</u>, graph the given equations and locate where the two lines intersect. The point of intersection is the <u>solution</u> to a system of linear equations.
Given linear system of equations:
Rewrite the second equation to make y the subject:
To graph a linear equation, find two points on the line by substituting two values of x into the equation. Plot the points and draw a straight line through them.
<u>Equation 1</u>
<u>Equation 2</u>
From inspection of the graph (see attached), the point of intersection is (6, -4).
