 Question 94529: How do I graph the following equations 1. 8y=3x+16, 2. 25x+30y=120 Write an equation in slope-intercept form for the line that contains the given points. 1.(2,10) and (3,35) 2. (-3,0) and(2,2) 3. (-2,5.5) and (0.5,-2) Please help, I don't understand this at all!! Click here to see answer by checkley71(8403)

 Question 94571: The converse of the Pythagorean theorem is also a true statement: If the sum of the squares of the lengths of two sides of a triangle is is equal to the square of the length of the third side, then the triangle is a right triangle. Use the distance formula and the Pythagorean theorem to determine whether the set of points could be vertices of a right triangle. (-3,1),(2,-1) and (6,9) How is this problem solved? Please show all the steps clearly. Thank you. Click here to see answer by Edwin McCravy(8908)
