Answer:

x = -9

Step-by-step explanation:

x = -9 would be the slope because when you see the two points for each coordinate there is no x value but we do see a straight line and we see that there is no y-intercept. So, x= -9 would be the answer. Hope this helps.

What is the sum of the interior angles of the polygon shown below

Ipatiy [6.2K]

Answer:

900

Step-by-step explanation:

The sum of the interior angles of a polygon with n sides is given by the formula:

$S=(n-2)180$

The polygon given has 7 sides. Substitute 7 for n. Thus:

$S=(7-2)180\\S=5(180)\\S=900$

The sum of the interior angles is 900 degrees.

What is the slope intercept form for the equation of the line provided?

denis-greek [22]

1. The slope intercept form is:

$y=mx+b$

Where $m$ is the slope of the line and $b$ is the intercept with the y-axis.

2. To calculate the slope, you can use the following formula:

$m=\frac{y_2-y_1}{x_2-x_1}$

Where:

$y_2=-1\\y_1=\frac{15}{2}\\x_2=\frac{1}{8}\\x_1=-2$

3. So:

$m=\frac{-1-(\frac{15}{2})}{\frac{1}{8}-(-2)}=-4$

4. Now you must find $b$ . Substitute any of the given points into the equation and solve for $b$ :

$\frac{15}{2}=-4(-2)+b\\\frac{15}{2}=8+b\\b=-\frac{1}{2}$

5. Therefore, the answer is the last option:

$y=-4x-\frac{1}{2}$
