Question
Jacob drove 184 miles in 4 hours, form a linear equation for the proportional relation, then the slope of the linear equation is
- 46 mph
- 61 mph
- 64 mph
- 41 mph
Hint:
Constant of proportionality is the same as the slope of a straight line passing through the origin. Using the formula m= 
we can find the value of slope or constant of proportionality. Here, we have to find the slope of the given linear equation using the given information in the question.
The correct answer is: 46 mph
In the question it is given that Jacob drove 184 miles in 4 hours.
We have to find the slope of the linear equation.
Here, x= time taken in hour and y= distance travelled in miles
So, x= 4 and y= 184
Slope= m= ....................(1)
Put the value of x and y in eq. 1.
Thus, the slope of the given equation is 46.
Therefore, the correct option is a, i.e., 46 mph.
