C because 6-3=3-1/4=2 3/4 so c
Answer:
y = -4x - 7
Step-by-step explanation:
we use the slope intercept formula given by; y = mx + b
b = y intercept, which is when x = 0
m = slope
so they tell us the slope.. we just need to find b - the y intercept.
y = mx + b
plug in your coordinates (-2,1)
1 = -4(-2) + b
1 = 8 + b
1 - 8 = b
-7 = b
put it all together.
y = -4x - 7
Answer:
Part 1) The speed is
Part 2)
Step-by-step explanation:
Part 1
<em>What is this speed on feet per second?</em>
we know that
1 hour=60 min
1 min=60 sec
so
1 hour=60*60=3.600 sec
1 mi=5,280 ft
we have
Convert mi/h to ft/sec
Part 2
At this speed how many feet will the parachutists fall during 10 seconds on free fall?
Multiply the speed by the time to obtain the distance
so
The answer is C
If you use the other coordinates instead of point (8,7), then you will not get a right angled traingle, but you will get other types of triangles. If you use (8,7), you will get a 90° and therefore a right angled triangle.
