Raphael graphed the system of equations shown. y = - 3 y = x - 0.8 What is the best approximation for the solution to this system of equations? (-3.2, - 3) (-2.9, - 3) (-2.2, - 3) (-1.9, - 3) Mark this and return

The answer is C (-2.2, - 3).

In order to find the ordered pair we must use what we know from the first equation in the second. We already know that y = - 3, so that goes into the second equation.

y = x - 0.8

-3 = x - 0.8

-2.2 = x

Given - --›

y = - 3

&

y = x - 0.8

So,

=> x = y + 0.8

=> x = - 3 + 0.8

=> x = - 2.2

Therefore, the best approximation for the solution to this system of equations is = (-2.2, - 3)
