PLEASE HELP!! ASAP use the discriminant to match the quadratic equation below with the correct graph of the related function. explain your reasoning
5x^2-10x-35=0

(choose a, b,c of d)

easy the answer is b

Step-by-step explanation:

the reason that is, is becuase I said so and I have a graphing calculator chow

for this case we have by definition, if two lines are perpendicular, then the product of their slopes is -1.

then, given the following line:

so,

we are looking for m_ {2}:

then, the line is given by:

we find "b" replacing the given point:

finally, the equation is:

option c

the functions have the same rate of change i think. i narrowed it down to this answer and "the rate of change of tour 1 is greater" but i got it wrong using that answer so im assuming its the answer above. (this is a question i also answered from the iready site if anyone needs a reference)
