Plz Check My Geometry
posted by Ariel on .
Out of 30 questions these few I struggled with. I put what I feel was right but to be sure I would like some one to check my answers and if there wrong redirect me on how to get the correct answer.( after the = is the answer i think it is.
1.) Given points A(4, 5), B(2, 3), C(0, 4) and D(5, 0), decide if AB and CD are parallel, perpendicular or neither.
=Neither
2.)Given the equations y = 1x + 7 and y = 3x  2, decide whether the lines are parallel, perpendicular or neither.
=neither
3.) Given the equations y = 4/3x  3 and y = 3/4x + 2, decide whether the lines are parallel, perpendicular, or neither.
=Perpendicular
4.) Which set of points are collinear?{options being A(1,5); B(2,6); C(4,7), A(0,0); B(1/2,3); C(1,5), A(4,2); B(0,4); C(2,5)
= A(4,2); B(0,4); C(2,5)
5.) Choose whether the lines given below are parallel, perpendicular or neither.4x  6y = 9; 3y  2x = 7j
= neither
6.) Choose whether the lines given below are parallel, perpendicular or neither.
4x  6y = 9; 4y + 6x = 12
=perpendicular
7.) Choose whether the lines given below are parallel, perpendicular or neither.4x  6y = 9; 3x  2y = 11
=neither
8.) Triangle Î”ABC has vertices A(2,5), B(8,1) and C(2,1) and is a right triangle. If the slope of AB is 2/3 and the slope of AC is 3/2, are the lines parallel, perpendicular or neither?
=perpendicular

3x=6
