Given:

The given expression is:

\log_b7-\log_b7

To find:

The single logarithm expression for the given expression.

Solution:

Quotient property of logarithm:

\log_bm-\log_bn=\log_b\left(\dfrac{m}{n}\right)

We have,

\log_b7-\log_b7

Using quotient property of logarithm, we get

\log_b7-\log_b7=\log_b\left(\dfrac{7}{7}\right)

\log_b7-\log_b7=\log_b\left(1\right)

Therefore, the required expression is \log_b\left(1\right).

Answer:

y = -2x + 3

Step-by-step explanation:

Let's just put the three points together.

(-1, 5) (-4, 11) (-7, 17)

First, let's find the slope with y2 - y1/x2 - x1

Plug in using (-1, 5) and (-4, 11)

11 - 5/-4 + 1 = 6/-3 (simplify)

-2 is the slope

Now plug in (-7, 17) in the equation to get b or the y-intercept)

y = mx + b

17 = -2(-7) + b

17 = 14 + b (subtract 14 on both sides)

3 = b

y = -2x + 3
