Question

Given the system has no solution, find the value of a/b. Show your work.

Answer 1

It’ll be C or B with no soul took by finding the value.

Answer 2

systems have no solution if they have the same slope, but different y-intercepts.

3/4x - 1/2y = 12, y = 2(3/4x - 12) = 3/2x - 24

ax - by = 9, y = (ax-9)/b, = ax/b -9/b

for the slopes to be the same, following must be true:

ax/b = 3/2x

a/b = 3/2

Correct answer is C
