Question

Lan graphs these equations and finds that the lines intersect at a single point,

(-2,-0.5).
Equation A: 4y - 3x = 4
Equation B: -2x + 8y = 8
Which statement is true about the values x = -2 and y = -0.5?
O
A. They are the only values that make both equations true.
O
B. They satisfy equation B but not equation A.
O
C. They show that the equations represent the same line.
O
D. They satisfy equation A but not equation B.

Answer 1

A. They are the only values that make both the equation true.

Explanation:

Equation A: 4y -3x = 4 ......... (1)

Equation B: - 2x +8y = 8 .......... (2)

From the graphs of those equations Ian finds that the lines intersect at (-2,-0.5).

So, this point is the common point of graph A and Graph B and this is the solution of equations (1) and (2).

So, we can conclude that they are the only values that make both the equation true. (Answer)
