Question

The line with a slope of -10/3 is perpendicular to a line with a slope of 0.3
Is this true or false? I guessed false..second opinion?

Answer 1

Can you rewrite .3 as a fraction?

Answer 2

uh, no, I guess not..:P

Answer 3

.3 is 3 tenths is 3/10

Answer 4

And since the negative reciprocal of -10/3 is 3/10 they are perpendicular.

Answer 5

It is true as the product of the slope of any two given lines produces 1, then the given lines are perpendicular

Answer 6

I mean produces -1

Answer 7

Thanks.

Answer 8

0.3=3/10 ┴ -10/3
