Question

-3x + y = -6 Y= 1/2x-1

Answer 1

Explanation:

Given system of equations in the question are,

-3x + y = -6

y =
`(1)/(2)x-1`

We can rewrite these equation as,

-3x + y = -6

y = 3x - 6 ------(1)

Table of input-output values for this equation will be,

x 0 1 2 3 4

y -6 -3 0 3 6

y =
`(1)/(2)x-1` ------(2)

Table for this equation will be

x 0 2 4 6 8

y -1 0 1 2 3

By plotting these points on the graph we find (2, 0) is a common point in both the tables,

Therefore, (2, 0) is the only one solution of the given system of equations.
