Which system of equations below has no solution?
a. y = 4x + 5 and y = 4x – 5
b. y = 4x + 5 and 2y = 8x + 10
c. y = 4x + 5 and y = 1/4 + 5
d. y = 4x + 5 and y = 8x + 10

A.  y = 4x + 5 and y = 4x – 5

Step-by-step explanation:

If the system of equations have the same slope and different y-intercept, then it will have no solution.

From the given options, let's find the slope and y-intercept.

A. y = 4x  + 5 and y = 4x - 5

Slope = 4 and y-intercepts are 5 and -5

Here we have the same slope and different y-intercepts. So, this is systems of equations have no solution.

B. y = 4x + 5 and 2y = 8x + 10 => y = 4x + 5

Both are the same equations.

This system  has an infinite number of solutions.

The answer is A)  y = 4x + 5 and y = 4x – 5
