So first, you need to identify the parts of this equation.
3x is the slope of the line, which is
.
-5 is the y-intercept. or the part of the line that touches the y-axis.
The first thing you want to do is plot the y-intercept. SO, go to the y-axis and find -5. Plot your point there.
Now, use the slope
to find your next plot. Since slope is
, you go up three, and over to the right one.
Now, draw a line connecting the dots. Your slope should be positive and look like > /

The answer is 3, since 3*3*3 equals 27


One way to find

is to notice that the part on the left hand side within the parentheses can be written as a square:

So you could write

Since these two expressions are equal, and the bases are the same, you know the exponents must be equal, with the exponent on the right hand side being 1. So

, or
