Equation #1: y = -2x 4; and the parallel line must pass through point (2, -3)
We need to find the line y= mx +b to y=-2x-4; that passes through (2,-3)
When a line is parallel to another line, both lines then have the same slope. I will use the ordered

Simplifying Radicals
In this discussion, you will simplify and compare equivalent expressions written both in radical
form and with rational (fractional) exponents. Read the following instructions in order and view
the example to complete this discussion:
This week I had the letter O, so I had to do number 42 ad 52.
#42 Factoring
y^2-3y-10=0
First, I started by Factoring my equation.
(y+2)(y-5)=0
After, this I took the factors and got this
y+2=0 or y-5=0
Then I used the Zero Factored property
y=-2 or y=5

I started by using the quotient rule, -2/3 (- 1/3) this lead me to get.
27^ (-1/3). After this I needed to get rid of the negative exponent, therefore I made it into the r
