Question

The equation of line m is 3x−5y=−4. what is the slope of a line that is perpendicular to line m? enter your answer in the box as a fraction in simplest form.

Answer 1

y = -5/3x

Explanation:

→ Rearrange to get y as the subject

3x + 4 = 5y

→ Divide both sides by 5

`(3x+4)/(5) =y` ⇔
`y = (3)/(5)x +(4)/(5)`

→ Negatively reciprocate gradient

y = -5/3x
