Answer:
[tex]Y = -X+5[/tex]
Step-by-step explanation:
To find the slope you need to do [tex]m = \frac{y2-y1}{x2-x1}[/tex]
Using that formula you will get [tex]m = -1[/tex]
Now you need to use the slope -1 and a given point (1,4) to substitute for x1 and y1 in point slope form
[tex]y-4 = -1*(x-1)[/tex]
now you need to solve for y
and you get....
[tex]y= -x + 5[/tex]
