Answer:

Step-by-step explanation:

10.   To solve for this, use the formula: 180*(n-2)

So, 180(n-2) = 2,340

Once n is solved for, that is the number of sides

11. Use the formula:

[180*(n-2)]/n

    (n represents the number of sides)

12. Think of the sum of all interior angles in a quadrilateral

Write an equation for the line in slope-intercept form​
quester [9]

Answer:

y = -3/1x + 2

Step-by-step explanation:

1. Find the slope

The points I will use are (-1,5) and (0,2), where x1 = -1, y1 = 5, x2 =0, and y2 =2.

y2-y1/x2-x1

2-5/0-(-1) = -3/1

2. Find the y-intercepy

y = mx + b

You can use any x or y point. I'll use (-1,5)

m= slope, which is -3/1

5= -3/1(-1) +b

5= 3 + b

Subtract 3 from 5 and 3 to get 2=b.

3. Rewrite in slope-intercept form

y = -3/1x + 2
