Answer: The equation for the two given points is y=x+b
Step-by-step explanation:
Step 1. First find the slope: 6-7/2-3 = -1/-1=1. The slope is just 1, or x. So for now, the equation is y=x+b
Step 2. We must find the y-intercept, or B. We can plug in any points to find b. Let's use (2, 6) (but you can use (3, 7) too, it doesn't matter) Plug 2 in for x, since 2 represents x, and then do the same for y. ---> 6=2+b.
Step 3. Simplify. 6=2+b. 6-2=2-2+b ---> b=4. Subtract both sides by 2 to get B.
The equation for the two given points is y=x+b
Hope this helps.

Answer:
Your graph is a parabola and needs to open down because the equation is negative. And your vertex is at (0,-4)
Question:
Evaluate the expression 5^x - 3^x for x=2
Answer:
5^x - 3^x for x=2 is 16
Step-by-step explanation:
Given
5^x - 3^x
x=2
Required
Evaluate
When fazed with question like this all you need is to substitute the value of x (or any other variable{s} used) in the expression.
Recall that x = 2
So, you have to substitute 2 for x in 5^x - 3^x
This gives
This can be further solved in 2 ways
1. Solve directly
= 
= 16
2. Expand using difference of two squares.
Difference of two squares is represented by
By comparison
becomes
For both ways, we'll arrive at the same answer.
Hence, 5^x - 3^x for x=2 is 16
