Answer:
Slope=6
Explanation:
Given a line that passes through the point (0,-4) and (1, 2), we are required to find the slope.
Whenever we are given two points on a line, we can find the slope of such a line by using the formula below:
![m=\frac{y_2-y_1}{x_2-x_1}](https://tex.z-dn.net/?f=m%3D%5Cfrac%7By_2-y_1%7D%7Bx_2-x_1%7D)
First, label the points.
![\begin{gathered} (x_1,y_1)=(0,-4) \\ (x_2,y_2)=(1,2) \end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%20%28x_1%2Cy_1%29%3D%280%2C-4%29%20%5C%5C%20%28x_2%2Cy_2%29%3D%281%2C2%29%20%5Cend%7Bgathered%7D)
Substitute the values into the formula.
![m=\frac{2-(-4)}{1-0}=\frac{2+4}{1}=6](https://tex.z-dn.net/?f=m%3D%5Cfrac%7B2-%28-4%29%7D%7B1-0%7D%3D%5Cfrac%7B2%2B4%7D%7B1%7D%3D6)
The slope of the line is 6.
It would be lets see 3.25 is the number so 185is divied by 50 miles

Answer:
The distance covered by the second cyclist in 45 minutes is (3/4·b + 9) miles
Step-by-step explanation:
The given parameters are;
The distance between the two cyclist when they begin biking away from each other = 7 miles
The first cyclist's speed = 12 miles per hour
The second cyclist's speed = 12 + b miles per hour
Therefore, we have;
The equation for distance covered, d = Speed × Time
The distance covered by the second cyclist in 45 minutes,
is given as follows;
45 minutes = 3/4 hour
= (12 + b) × 3/4 = (3/4·b + 9) miles
The distance covered by the second cyclist in 45 minutes = (3/4·b + 9) miles.
