and for x near 0, sin(x) is very similar to x.
Answer:
y=-5x+12
Step-by-step explanation:
Since slope-intercept form is y=mx+b, m is the slope, and b is the y-intercept. We substitute m for -5, since it is the slope, and we substitute 12 for b, since it is the y-intercept. I hope this helps!
Every hour is 60 minutes, there is 43 minutes before 12:00, and 155 minutes after 12:00
