Answer:
Step-by-step explanation:
The y-intercept is super easy. The y-intercept exists when x = 0; therefore, the point given where x = 0 is found in (0, -15). That means that the y-intercept is -15. Easy enough. Now, the slope.
Since all these points are on the same line, using any 2 of them in the slope formula will get us the slope. I picked the first 2 points (1, -19) and (-4, 1):
The y-intercept is -15 and the slope is -4
Slope is 0
Step-by-step explanation:
- Step 1: Find slope using the formula for slope, m = (y2 - y1)/(x2 - x1) Here, x1 = -2, y1 = -1, x2 = 5 and y2 = -1
⇒ m = (-1 - -1)/(5 - -2)
= 0/7 = 0
Answer:
The equation that can be used to determine m, the number of minutes it will take the helicopter to reach the hospital is .
Step-by-step explanation:
We are given that a medical rescue helicopter is flying at an average speed of 172 miles per hour toward its base hospital. At 2:42 p.m., the helicopter is 80 miles from the hospital.
As we know that the Distance-Speed-Time formula is given by;
Here, Distance = 80 miles
Speed = 172 miles per hour
Time = m (the number of minutes)
Firstly, as we can see that the speed is in miles per hour but the time is in minutes, so we will convert the time in hours, i,e;
Time =
So,
m = 27.91 ≈ 28 minutes.
Hence, it will take 28 minutes for the helicopter to reach the hospital.
