Question

One equation in a system is y = 2x - 4. Which equation gives the system no solution?y = 2x - 4y = 2x + 9y = 1/4x - 4y = -2x + 4

Answer 1

Answer is choice B y = 2x + 9

Step-by-step explanation

step1: I have to compare the equation given to the equation of a straight line

from the question, we have

y = 2x - 4

c/f y = mx + c

hence m = 2 and c = -4

so the choice B: y = 2x + 9

Gives : m = 2 and c = 9

Hence since m is the same that is (= 2) and c is different, hence the equation has no solution then.

The answer is choice B
