Answer:
y = 4/5 x - 2 1/5
Step-by-step explanation:
1. Find the slope:
1 - 5/ 4 - 9 = 4/5 = m
2. Find b by plugging in the m and one of the points given into y = mx + b
1 = 4/5 ( 4) + b
1 = 16/5 + b
-2 1/5 = b
3. Write the equation using the m and the b you just found
y = 4/5 x - 2 1/5

Answer:
R = 1.2%
Step-by-step explanation:
<u>Given the following data;</u>
Principal = 425
Time = 2
Simple interest = 10.20
To find the annual interest rate;
Mathematically, simple interest is calculated using this formula;
Where;
- S.I is simple interest.
- P is the principal.
- R is the interest rate.
- T is the time.
Substituting into the equation, we have;
Cross-multiplying, we have;
<em>R = 1.2%</em>
<em>Therefore, the annual interest rate is 1.2 percent. </em>

<h2>
Mishka's speed = 14 km/hr</h2><h2>
Current speed = 2 km/hr</h2>
Step-by-step explanation:
Let the speed of rowing be r and speed of current be c.
If he rows with the current, Mishka rows 48 km in 3 hours.
Relative speed = r + c
Distance = 48 km
Time = 3 hours
48 = 3 x ( r+c)
r + c = 16 ---------------------------eqn 1
If he rows against the current, it takes 4 hours to travel the same distance.
Relative speed = r - c
Distance = 48 km
Time = 4 hours
48 = 4 x ( r - c)
r - c = 12 ---------------------------eqn 2
eqn 1 + eqn 2
2r = 28
r = 14 km/hr
Substituting in eqn 1
14 + c = 16
c = 2 km/hr
Mishka's speed = 14 km/hr
Current speed = 2 km/hr
