Answer:
I think it is A
Step-by-step explanation:
This is in point slope form.
Basically, point-slope form is:
y -
= m(x -
)
With
and
being points on the line.
So therefore, in this equation, you see 5 and 1 in those places.
However, since you're subtracting
and
, and in the equation you seem to be adding 5 and adding 1, this means that the points must be -5 and -1 for it to work.
So therefore:
(-1, -5) is a solution of the equation y + 5 = 2(x + 1)
The zeros of this function is when y = 0.
(x, 0) and (x,0)
Looking on the graph
It would be (3,0) and (6,0)
The solution is x = 3, x = 6
