Answer:
first one with -1...21
Step-by-step explanation:
only one that follows quadratic formula format
Answer:
B, C
Step-by-step explanation:
I love slope
Answer:
<C=48 because 90-42=42 as in the other side of the triangle.
<B=42 because vertical angles are always congruent.
<B+<D=90 because <D is 48 because it is vertical to <C
Answer:
None of the points is a solution
The question doesn't look logical correct, check closely
Step-by-step explanation:
With the points ;
(1,-1)(1,−1)
The slope is = ( -1-( -1))/( 1-1)= infinity
Similarly if you do same with
5,-7)(5,−7) ; the slope would be infinity
