 Question 179578: Homework Question: Find the area of the triangle enclosed by the lines, 1 . y=2/3x -7/3 2. y =-1/2x+3/2 3. y=-6x-5 Find the points of intersection and then map on a graph. I started out by finding the x and y coordinates of each line to plot on the graph. The triangle I get is so small that I know I need to find the points of intersection but I am not sure how. Then I guess find the side length I think and lastly the area but unsure of what path to take. I am a middle grade teacher working towards my endorsement and taking class. This was the homework the teacher gave. He made it up, it did not come from a text. I would appreciate any help you can give. Thanks!!! Click here to see answer by Fombitz(13828)

 Question 180479: hey maybe someone could help me with these three algebra problems, i have been sitting on them almost all day, and my homework is do by monday (ill get a D if i dont give my homework up this time:( )so its sorta important to get them done, but i dont understand them :/ so enough of the small talk ill just tell you which algebra problems they are; 1) find an equation of the line point slope form that passes through (4,3) and is parallel to the line 3x-y=7 2) what is the equation in standard form of the line through (4,1) an (-2,3)? 3) find the equation of the line with x-intercept 5 and y-intercept 8 it would be great if someone could help me with these! :) Click here to see answer by Alan3354(31518)
