Question

Billy graphed the system of linear equations to find an approximate solution.

y = x +
y = x – 3


Which points are possible approximations for this system? Check all that apply.

(1.9, 2.5)
(2.2, –1.4)
(2.2, –1.35)
(1.9, 2,2)
(1.9, 1.5)

Answer 1

Answer:

(2.2, –1.4)  and (2.2, –1.35)

Step-by-step explanation:

The solution to this system of equations would be the point of intersection of the lines.  This point is a little past 2 on the x-axis and a little below 1 on the y-axis.  The only two points in our choices that fit these criteria are (2.2, –1.4)  and (2.2, –1.35).

Answer 2

The solution of the equation will be (2.2, -1.35). Then the correct option is C.

What is the solution of the equation?

The solution of the equation means the value of the unknown or variable.

Billy graphed the system of linear equations to find an approximate solution.

y = -(7/4)x + 5/2  …1

y = (3/4)x – 3      …2

From equation 1 and 2, we have

(3/4)x – 3 = -(7/4)x + 5/2

(3/4 + 7/4)x = 5/2 + 3

10/4 x = 11/2

x = 2.2

Put in equation 1, we have

y = (3/4)(2.2) – 3

y = 1.65 – 3

y = –1.35

Then the correct option is C.
