Answer:
Slope, m = 1.5
y-intercept, c = -4.3
Step-by-step explanation:
We are given the following equation in the question:

where F is foot length in millimeters and h is height in centimeters.
Comparing equation to a general linear equation:

where m is the slope and c is the y - intercept.
Slope, m = 1.5
y-intercept, c = -4.3
Interpretation of slope:
Slope tells us about the rate change. So, when the there is a unit increase in height the foot length changes by 4.3 foot.
Interpretation of y-intercept:
y-intercept is the value of F when height,h is zero that is

Answer:
<h2> 5mile per hour</h2>
Step-by-step explanation:
Step one:
given data
distance= 1/4mile
time taken= 1/20 hour
Step two:
Required
speed
we know that speed is
speed= distance/time
substituting
speed= 1/4/1/20
speed=1/4*20/1
speeed=20/4
speed=5mile/hour
The option a sis correct, the speed is 5mile per hour
