The slope is 0!! any horizontal line, like y = 1, y = 2, y = any other number, has a slope of 0. because it's a horizontal line, it's flat, so there isn't any incline or decline. just as a note: vertical lines (x = 1, etc.) have an undefined slope.

Answer:
x = 27
Step-by-step explanation:
3x - 4y = 65
3x = 65 + 4y
<em><u>Find x, when y = 4</u></em>
3x = 65 + 4 (4)
3x = 65 + 16
3x = 81
x = 27             ![[ \ x = \frac{81}{3}\ ]](https://tex.z-dn.net/?f=%5B%20%5C%20x%20%3D%20%5Cfrac%7B81%7D%7B3%7D%5C%20%5D) 
                     
 
        
             
        
        
        
Using proportions, according to the ratio of the partition, it is found that the location of point g is at 3.
<h3>What is a proportion?</h3>
A proportion is a fraction of a total amount, and the measures are related using a rule of three.
In this problem, point g partitions the directed line segment from d to f into a 5:4 ratio, hence:

We have that d = -2 and f = 7, hence:


g + 2 = 5.
g = 3.
