Answer: Choice D

(a-e)/f

=======================================

Explanation:

Points D and B are at locations (e,f) and (a,0) respectively.

Find the slope of line DB to get

m = (y2-y1)/(x2-x1)

m = (0-f)/(a-e)

m = -f/(a-e)

This is the slope of line DB. We want the perpendicular slope to this line. So we'll flip the fraction to get -(a-e)/f and then flip the sign from negative to positive. That leads to the final answer (a-e)/f.

Another example would be an original slope of -2/5 has a perpendicular slope of 5/2. Notice how the two slopes -2/5 and 5/2 multiply to -1. This is true of any pair of perpendicular lines where neither line is vertical.

Write in point-slope form an equation of the line that passes through the given point and has the given slope. Point: (4, 8); m

Ainat [17]

Answer:

$\mathsf{y-8=\cfrac{3}{4}(x-4)}$

Step-by-step explanation:

Hi student, let me help you out!

<u>.. .. .. .. .. .. .. .. .. .. .. .. .. .. .. .. .. .. ... ... ..... ........ ...... ... ......... .... ....</u>

<u></u>

First, let's recall the point-slope form equation: ↪ $\mathrm{y-y_1=m(x-x_1)}$ .

<u>where: </u> y₁ = y-coordinate of the point (the second coordinate), m=slope, x₁=x-coordinate (the first coordinate).

Let's stick in the values accordingly. We obtain the following: $\mathrm{y-8=\cfrac{3}{4}(x-4)}$ , which is our point-slope form equation.

Hope this helped you out, ask in comments if any queries arise.

Best Wishes!
