Question

Which of the following graphs shows the solution to the system of equations?

y = 5x – 1
y = x + 3

Answer 1

The answer is D for the question above.

Answer 2

The graph which shows the solution to the system of equations

y = 5x – 1

y = x + 3 is:

Graph D

Explanation:

We are given system of equations:

y = 5x – 1

y = x + 3

on subtracting first equation by second, we get

0=4x-4

i.e. x=1

when x=1 y=4

Hence, solution of this system of equation is:

(1,4)

Which is represented by graph D
