Question

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?

Answer 1

Answer:

C.) (–2.2, –3)

Step-by-step explanation: keep it simple

Answer 2

Answer:

(-2.2,-3)

Step-by-step explanation:

We have been given a system of equations and we are asked to find the best approximation for the solution to this system of equations.

$y=-3...(1)$

$y=x-0.8...(2)$

We will use substitution method to solve for the system of equations.

Upon substituting equation (1) in equation (2) we will get,

$x-0.8=-3$

Upon adding 0.8 to both sides of our equation we will get,

$x-0.8+0.8=-3+0.8$

$x=-2.2$

Therefore, the best approximate value of x is -2.2 and approximate value of y is -3.
