What is the best approximation of the solution to the equations that these two lines represent?
2 answers:
Answer: 1) (3,1.5)
2) (1,1.5)
Step-by-step explanation:
We know that the solution of system of two linear equation is the point on graph where the lines of the equations intersect.
- From the first picture, we can see that the x-coordinate of the intersection lies between 2 and 4 and the y-coordinate lies between 1 and 2.
The approximate value for x- coordinate = Mid point between 2 and 4
=3
The approximate value for y- coordinate = Mid point between 1 and 2
=
⇒ The best approximation of the solution to the equations =(3,1.5)
- From the second picture, we can see that the x-coordinate of the intersection is 1 and the y-coordinate lies between 1 and 2.
The approximate value for y- coordinate = Mid point between 1 and 2
=1.5
⇒ The best approximation of the solution to the equations =(1,1.5)
