Hello!

As you can see, 3x+9 makes a right angle, or 90 degrees. We can turn this into an equation and solve for x.

3x+9=90

First we subtract 9 from both sides.

3x=81

Then divide both sides by 3.

x=27

Therefore, x=27.

I hope this helps!

Draw a line representing the "run" and a line representing the "rise" of the line. State the slope of the line in simplest form.
Igoryamba

Answer:

The answer is "\bold{\frac{9}{13}}"

Step-by-step explanation:

In this question, the image file is missing, which is defined in the attached file. please find it.

\to raise= y_2-y_1

             =-1-(-10)\\\\=-1+10\\\\=9

\to run= x_2-x_1

          =9-(-4)\\\\=9+4\\\\=13

\to \text{formula for slope} =\frac{rise}{run} =\frac{9}{13}

A line with a slope of -1/3 passes through the point (9,3). What is its equation in point-slope form?
amm1812

The point-slope form:

y-y_1=m(x-x_1)

We have:

(9,\ 3)\to x_1=9,\ y_1=3\\\\m=-\dfrac{1}{3}

Substitute

y-3=-\dfrac{1}{3}(x-9)
