Question

Ermine whether the give

. 2x - 3y = 9
4x - 5y = 15
determine wether the given lines are parrallel perpendicular or neither

Answer 1

Neither

Explanation:

Rewrite the equation in the form slope intercept

2x - 9 = 3y

y = (2/3)x - 9/2

so the slope is 2/3

for the second equation

4x - 15 = 5y

y = (4/5)x - 15/4

so the gradient is 4/5

since the slip of the lines are neither parallel nor perpendicular to each other.

so the answer is neither.
