Option 1: is the correct answer.

Step-by-step explanation:

The slope-intercept form of a line is given as:

Here m is the slope and b is the y-intercept

m is calculated using the formula

Given points are:

Putting the values in the formula

Putting m=-2/3 in equation

Putting (9,-1) in equation

Putting the value of b

Hence,

Option 1: is the correct answer.

logv3(x+2)=1

rewrite in exponential form:

logb(x) = y is equal to b^y =x

b = 3, y = 1

now solve for x:

3^1 = x+2)

x = 3-2

x = 1

see the picture for the graph.

c.

step-by-step explanation:

she should of added 9^2 and 12^2. that is because it is a^2+b^2=c^2. c^2 is the hypotenuse and should always be bigger than the other two numbers. which is why she should of added 9 squared and 12 squared together instead of 15 squared.
