Identify the equation in point slope form for the line perpendicular to y= -1/3x-6 that passes through (-1,5).

A. y - 5 = 3(x + 1)

Step-by-step explanation:

y = -1/3 x - 6

This line, slope = -1/3

Perpendicular lines, slope is opposite and reciprocal, so slope = 3

Equation that passes thru (-1,5)

y - 5 = 3(x + 1)

For this case we have that if two lines are perpendicular, then it follows that:

We have

So:

Then, the equation is of the form:

We have the point:

We replace:

Option A

step-by-step explanation:

∆abc has the points a(1, 7), b(-2, 2), and c(4, 2) as its vertices. formed with the point d(1, 2) as its third vertex, then ∆abd is triangle.

this may not be at all, but i use the same website you're using for school, and if i'm stuck doing one of these i try to look for it on the section.
