Answer:

The equation representing the left table is

y = 1.5x - 6

The equation representing the right table is

y = -4x + 6.1

The solution to the system of equations is

(2.2, -2.7)

A system of linear equations contains multiple linear equation

  • The equation of the left table is [tex]y =1.5x -6[/tex]
  • The equation of the right table is [tex]y =-4x +6.1[/tex].
  • The solution to the system of equations is (2.2,-2.7)

The left table

The slope is calculated as:

[tex]m = \frac{y_2 -y_1}{x_2 -x_1}[/tex]

Using the points on the table, we have:

[tex]m = \frac{-4.5 --6}{1-0}[/tex]

[tex]m = \frac{1.5}{1}[/tex]

[tex]m = 1.5[/tex]

So, the equation is calculated using

[tex]y =m(x -x_1) + y_1[/tex]

This gives

[tex]y =1.5(x -0) -6[/tex]

Open bracket

[tex]y =1.5x -6[/tex]

The right table

The slope is calculated as:

[tex]m = \frac{y_2 -y_1}{x_2 -x_1}[/tex]

Using the points on the table, we have:

[tex]m = \frac{2.1 -6.1}{1-0}[/tex]

[tex]m = \frac{-4}{1}[/tex]

[tex]m = -4[/tex]

So, the equation is calculated using

[tex]y =m(x -x_1) + y_1[/tex]

This gives

[tex]y =-4(x -0) +6.1[/tex]

Open bracket

[tex]y =-4x +6.1[/tex]

The solution

We have:

[tex]y =1.5x -6[/tex]

[tex]y =-4x +6.1[/tex]

Equate both equations as follows

[tex]-4x + 6.1 = 1.5x - 6[/tex]

Collect like terms

[tex]-4x -1.5x = -6.1 - 6[/tex]

[tex]-5.5x = -12.1[/tex]

Divide both sides by -5.5

[tex]x = 2.2[/tex]

Substitute 2.2 for x in [tex]y =1.5x -6[/tex]

[tex]y =1.5 \times 2.2 -6[/tex]

[tex]y =-2.7[/tex]

Hence, the solution to the system of equations is (2.2,-2.7)
