Question

A line with the equation of y=1x/10-1 what is the perpendicular lines that goes through (3,9)​

Answer 1

Explanation:

Perpendicular lines are lines whose slopes are the negative reciprocal of each other.

So, in this case, the other line's slope is
`-10`

Now we can use

`y = mx + b\\y = -10x + b\\9 = -10(3) + b\\9 = -30 + b\\b = 39\\y = -10x + 39`
