Question 342420: Three points that form the vertices of a triangle are: (-4,3), (-7, -1), (3, -2)
Use the distance formula to determine if the triangle is a right triangle.
Please explain in detail how to get the answer.
Solution manual is saying to use the Slope calcualtion m = (y sub2 - y sub1) / (x sub2 - x sub1).
I thought the distance formula was d = square root of (x sub2 - x sub1) + (y sub2 - y sub1)???

Question 342390: I am not sure if I am plugging in my test points correctly. FOr example on y<-x+1 I substituted 0 for x and y which gave me the answer 0<-1. I assume I should change that to 1>0 to put the x on the left side of the inequality? Is that correct? Can you just show me how you would work this, how you would enter test points and what the graph should look like in the end?
Thanks,

Question 343478: I really need help with this. I have never been in an algebra class until I started back to school. Any help that I can get to help me understand how this is to be worked would be greatly appreciated.

2. The coordinate graph of the backyard shows the location of the trees, plants, patio, and utility lines. If necessary, you may copy and paste the image to another document and enlarge it.
a. What are the coordinates of Tree A, Plant B, Plant C, Patio D, Plant E, and Plant F?

b. The water line is given by the equation

Imagine you want to put a pink flamingo lawn ornament in your backyard. You want to avoid placing it directly over the water line in case you need to excavate the line for repairs in the future. Could you place it at the point (-4,-10)?
c. What is the slope and y-intercept of the line in Part b? How do you know?
d. Imagine you want to add a sprinkler system and the location of one section of the sprinkler line can be described by the equation

Complete the table for this equation.
x y (x,y)
