(7, 1) and (1,8)
slope = (8 - 1)/(1-7) = -7/6
so
y - 1 = -7/6(x - 7)
y - 1 = -7/6 x + 49/6
y = -7/6 x + 55/6
answer
A. first one
y = -7/6 x + 55/6
Using the power rule, the derivatives are given as follows:
a)
.
b)
.
<h3>What is the power rule for a derivative?</h3>
Suppose we have a power function given by:

The derivative of the function is given by:

Item a:
The function is:

Then the derivative is:

When x = 2, the derivative is:

Item b:
The function is:

Then the derivative is:

When x = 3, the derivative is:
