When we're given a point, , the  value corresponds to the distance from the origin horizontally (with negative distance corresponding to moving to the left). Thus, our  value in this case is  and thus that is our answer. 

The y-intercept is the point at which the line intersects the y-axis.

It does this at .

We plug  in for  in our equation, , to give us .

Anything multiplied by  is , so .

Our coordinates for the y-intercept are .

The first number in the ordered pair indicates how far left or right the point resides from the origin. The second number in the ordered pair indicates how far up or down the point resides from the origin. Numbers that are positve are located on the right side and above the origin while negative numbers are located to the left of or below the origin. This point resides to 2 units to the right and 1 unit above the origin.

The first number in the ordered pair indicates how far left or right the point resides from the origin. The second number in the ordered pair indicates how far up or down the point resides from the origin. Numbers that are positve are located on the right side and above the origin while negative numbers are located to the left of or below the origin. This point is located 3 units to the left and 7 units above the origin.

The first number in the ordered pair indicates how far left or right the point resides from the origin. The second number in the ordered pair indicates how far up or down the point resides from the origin. Numbers that are positve are located on the right side and above the origin while negative numbers are located to the left of or below the origin.This point is located 4 units to the right and 5 units below the origin.

To find the slope of a line with two points you must properly plug the points into the slope equation for two points which is

We must then properly assign the points to the equation as  and .

In this case we will make  our  and  our .

Plugging the points into the equation yields 

Perform the math to arrive at 

The answer is .

In the standard form of a line  the slope is represented by the variable .

In this case the line  has a slope of .

The answer is .

The equation of the line is written in slope-intercept form, , where  is the slope and  is the y-intercept. In this example, the y-intercept is a negative number.

To find the slope of a line with two points we must properly plug the points into the slope equation:

We must then assign the variables  and .

In this case we will plug in for  and  for .

Plugging the points into the equation yields .

Perform the math to arrive at .

The answer is.

To find the angle of any regular polygon you find the number of sides . For a pentagon, .

You then subtract 2 from the number of sides yielding 3.

Take 3 and multiply it by 180 degrees to yield the total number of degrees in the regular pentagon. 

Then to find one individual angle we divide 540 by the total number of angles 5, 

The answer is .
