**Algebra 2**

arrange the equations into the form ax + by = c 1. -14x = -632 - 26y ---> 14x - 26y = 632 slope = 14/26 = 7/13 y = (7/13)x - 316/13 ---> 7x - 13y = 316 slope = -7/-13 = 7/13 since the slopes are equal, they must be parallel. To be perpendicular, their slopes must be ...

**algebra**

The solution to a system of linear Eqs is the point where they intesect. If the lines are parallel, they cannot intersect and, therefore, have no solution. If we solve the Eqs of two parallel lines, the answer will not make sense. For example, we could get -15 = 30 which is ...

**Math**

midpoints: mPQ=A: (-3,2) mQR=B: (-2,-3) mRS=C: (3,-1) mSP=D: (2,4) check slopes: AB: -5 BC: 2/5 CD: -5 DA: 2/5 parallel in pairs. OK.

**math**

this problem seems with too many numbers that i don't know where to start. or even how.I have to answer the problem on top not the one that says number 27. The problem: Geometry. For the floor plans given in exercise 27, determine whether the side through the points (2,3) and...

**Math - vector equation of a parallelogram**

Are you sure your points are correct? None of the line segments form parallel lines, (slopes are not equal)
