The horizontal graph parallel to the x-axis is described by equation:

**y = b,** where b is the y-intercept at (0,y), and slope (m) = 0.

1) The equation 5 units above the point (2,2):

To find the y-intercept given the points, when y=2:

y- intercept (b) = 2 + 5

**y - intercept (b) = 7 **

**Since the equation for horizontal graph is y = b, therefore the equation ****5 units above point (2,2) is:**

**y = 7**

2.) 5 units below the point (2,2):

To find the y-intercept given the points, when y=2:

y-intercept (b) = 2 - 5

**y - intercept (b) = -3**

Since the equation for the horizontal graph is y = b, therefore, the equation 5 units below point (2,2) is:

** y = -3**

**ANSWER:**

**1) y = 7**

** m (slope) = 0**

** Domain = {x / x is an element of real numbers}**

** Interval notation: (⁻∞ , ⁺∞)**

** Range = {y / y = 7}**

** = {7}**

**2) y = -3**

** m (slope) = 0**

** Domain = {x / x is an element of real numbers}**

** Interval notation: (⁻∞, ⁺∞)**

** Range = {y / y= -3}**

** = {3}**
