The slope of line:
-6x-3y = 12

Which linear equations have an infinite number of solutions? check all that apply.  (x  –  3/7)  =  2/7(3/2x  –  9/14)8(x  +  2)  =  5x  –  1412.3x  –  18  =  3(–6  +  4.1x)(6x  +  10)  =  7(x  –  2)4.2x  –  3.5  =  2.1 (5x  +  8)

#1-20 state whether the angles are alternate interior, alternate exterior, vertical, or corresponding angles.

Solve each quadratic equation by factoring and using the zero product property. x^2 - 8x + 30 = 3x
