Question

The system of linear equations by graphing

Answer 1

(1,2)

or

x = 1

y = 2

Explanation:

To solve the system of two linear equations by graphing, plot the graphs of both lines (linear equation represents the line).

1. The line with the equation
`5x+y=7` intersects the y-axis at point (0,7) and the x-axis at point
`((7)/(5),0)`. Connect these to points with the straight line.

2. The line with the equation
`2x+y=4` intersects the y-axis at point (0,4) and the x-axis at point
`(2,0)`. Connect these to points with the straight line.

he point of intersection (1,2) of these two lines is the solution to the system of two linear equations.
