Answer:
slope = 3
Step-by-step explanation:
Use the coordinates of the points to determine the slope.
Rahul use addition property of equality in step 2.
Solution:
The image of the question is attached below.
Step 1:

combine like terms together.

To make the denominator same multiply and divide 2x by 5.
Step 2:

By addition property of equality, add
on both side of the equation.

Step 3:

Step 4:
Multiply by
on both side of the equation.

Hence Rahul use addition property of equality in step 2.
Answer:
A linear function is written as:
y = a*x + b
Where a is the slope and b is the y-intercept.
An exponential equation is written as:
y = A*(r)^x
Where A is the initial quantity and r is the rate of growth.
If a and A are both positives, the similar characteristic of both types of functions is that as x increases, then the value of y will also increase. Then both functions are increasing functions.
They are different in how they increase, while a linear function increases at a constant rate, an exponential function increases slow at the beginning and really fast as x increases, as you can see in the image below where we compare the two types of functions, the green one is the linear function, and the blue one is the exponential function.
Answer:
slope: 1/4
y-intercept: 1
