Answer:
[tex]\Large \boxed{ -x+65}[/tex]
Step-by-step explanation:
Two points are (0, 65) and (10, 55)
Calculate slope m
[tex]\displaystyle m=\frac{y_2 - y_1}{x_2 - x_1}[/tex]
[tex]\displaystyle m=\frac{55-65}{10-0}=-1[/tex]
Use slope-intercept form
[tex]y=mx+b[/tex]
[tex]y=-1x+b[/tex]
b is the y-intercept, y-intercept is (0,65)
[tex]y=-1x+65[/tex]
