Which is the graph of y = 2.5x?<br><br> A.<br><br><br> B.<br><br><br> C.<br><br><br> D.

Thepotemich [5.8K]

The answer is D. because first you got solve the problem.

y=2.5x
(turn y to 0)
0= 2.5x
÷2.5 ÷2.5
_________
0=x

So we got one answer (0,0)

y=2.5x
(turn x to 0)
y= 2.5(0)
y=2.5

(2.5, 0)

When you do (0,0) (2.5,0) on the graph it will look like D.)

Derive the equation of the parabola with a focus at (_5, 5) and a directrix of y = -1.

mars1129 [50]

Answer: Option D is correct.

Step-by-step explanation:

Since we have given that

focus = (-5,5)

and a directrix y= -1

Since, equation of parabola in this case will be

$(x-h)^2=4.a(y-k)$

Now, here

$y=k-a=-1\\\\\text { focus =(h,k+a)}\\\\\text{So,} k+a=5\\\\\text{ by solving these two equation , we get }\\\\a=3\text{ and } k=2$

So equation will be

$(x+5)^2=4\times 3(y-2)\\\\(x+5)^2=12(y-3)\\\\y=\frac{1}{12}(x+5)^2+2$

So, option D is correct .
