Question

Line $j$ is perpendicular to $\frac{y}{3}+\frac{2x}{5}=2$. What is the slope of line $j$?

Answer 1

`(1)/(3)`

Explanation:

The slope of
`(y)/(3)+(2x)/(5)` is -3. When a line is perpendicular to another, it's slope will be the negative reciprocal of the other line. -3 could also be written as
`-(3)/(1)` , and if you take the reciprocal, it would be
`-(1)/(3)` , and the negative form of this (since a negative plus a negative is a positive) would be
`(1)/(3)` .

Answer 2

5/6
