The linear function y = 1.2x represents Alberto’s speed, y, in meters per minute, when his stride rate is x steps per minute.Explain what the slope and y-intercept of the linear model represent in the context of the situation.
Answers
Answer with explanation:
The linear function is given by:
where y represents Alberto's speed in meters per minutes.
when his stride rate is x steps per minute.
We know that for any linear function of the type:
m represents the slope and c represents the y-intercept of the function.
- Here m=1.2 and c=0
i.e. the slope represents the stride rate of Alberto i.e. the rate at which he is walking.
- and the y-intercept represents the speed of Alberto when he took 0 steps i.e when x=0.
It represents that his speed is 0 meter per minutes when he did not took any step.

x is doubled
then 5 is subtracted means
2 times x-5
2x-5
result is 37
2x-5=37
solve
add 5 to both sides
2x+5-5=37-5
2x+0=42
2x=42
divide both sides by 2
2/2x=42/2
1x=21
x=21
the number si 21
If you know the answer is 37, you need to therefore, add 5 (because it says it has been subtracted in the question)
This will give you 42.
Because the question then says this number has been doubled - you should halve it.
This will give you 21.
To check your answer, use this number, and do as the question shows you...
21 x 2 - 5. Does this equal 37?
Yes, then you must be correct :)
