Answer:

Step-by-step explanation:
Find the slope using the points, (1, -3) and (3, 1):

m = 2
Find the y-intercept (b) by substituting x = 1, y = -3, and m = 2 in 


Subtract 2 from both sides



Plug in the value of m and b into the slope-intercept form equation,
.
Thus:

Hey there!
The equation we have been given is 5 - n/3 = -4.
Let's start by subtracting 5 from each side.
-n/3 = -9
Multiply each side by 3.
-n = -27
Multiply each side by -1.
n = 27
Check our answer.
5 - 27/3 = -4
5 - 9 = -4
-4 = -4
The value of n is 27.
Hope this helps!
