Answer:
y = 10/3x - 18
Step-by-step explanation:
1. Take the reciprocal of the slope given to you, 3/10 -> 10/3
2. Write your new equation with the new slope in slope-intercept form: y=10/3x+b
3. Use the point given to find your y-intercept / b: -8 = (10/3)(3)+b
-8 = 10 + b
-18 = b
4. Plug b back into your new equation. y = 10/3x - 18
so every hour it droped 2 degrees and it did this for eight hours you could times 2 by 8 and get 16 then minus it from 72
Answer:
y=-5x-4
Step-by-step explanation:
y=mx+b
-5=-5m+b
-5=-1+b
b=-4
y=-5x-4
