Question

Which line has an undefined slope?
y = x-5
3y - 6x = 0
x= 10
y = -5

Answer 1

x = 10

Explanation:

Y = x-5 has a slope of 1

3y - 6x = 0 is a clear linear equation with a Y-intercept of 0

y = -5 has no slope

x = 10 is a line going straight up and intersects the point (10, 0)

Which is an undefined slope
