Question

Solve graphically this linear system of equations
`\left \{ {{x=3} \atop {y+1=0}} \right.`

Answer 1

(3,-1)

Explanation:

The given equations are :

x = 3 ..(1)

y+1 = 0 ....(2)

We need to solve the equations graphically. x = 3 means draw a line parallel to y axis.

For y+1=0

y = -1

Draw a line parallel to the negative x axis. The attached figure shows the graph for the given equations. The solution is (3,-1).
