Question

The lines in which pair are perpendicular?

y=−15x+2 and y=−5x+1

y=15x+2 and y=5x+1

y=23x+2 and y=−32x+2

y=23x+1 and y=32x+2

Answer 1

Step-by-step explanation:

For the lines to be perpendicular, the product of their slopes should be equals to -1

All equations are in y = mx + c form but none of the equations have m1 * m2 = -1

Hence none of them are perpendicular

Either that or your question is wrong
