ANSWER
EXPLANATION
The equation of a parabola in factored form is
where 'a' is the leading coefficient and 'm' and 'n' are the zeros.
From the question, the zeros of the parabola are 6 and −5.
This implies that,
We plug in these zeros to get:
If (-1, 3) is a point on the graph of this parabola,then it must satisfy its equation.
We substitute x=-1 and y=3 to obtain:
The first choice is correct.
Answer:
Step-by-step explanation:
To use the SAS similarity theorem, you must show proportionality between corresponding sides, and congruence of the angle between them.
The answer shown above is the only answer choice that mentions an angle.

<em>Comment on other choices</em>
Choice B shows the three sides are proportional, so would be useful if the SSS similarity theorem were to be invoked. It isn't helpful for the using the SAS similarity theorem.
Choices C and D get the proportion statements wrong.
