For every 10 unit increase in x, there's a 6 unit decrease in y.
Your slope is -6/10 or -3/5.
This gives us y = -3/5 x + b.
Using (25,94), we can solve for b:
94 = -3/5 (25) + b
94 = -15 + b
109 = b
So, y = -3/5 x + 109.
Let's double check it works with x = 45:
y = -3/5 (45) +109
= -27 + 109
= 82
Looks like we're good.
