Answer:
equation: y=-4x-7
Step-by-step explanation:
y=-4x+b
solve for b using given coordinates on the line (-3, 5)
5=-4(-3)+b
b=-7

Answer:
The equation
represents the equation of the parabola with focus (-3, 3) and directrix y = 7.
Step-by-step explanation:
To find the equation of the parabola with focus (-3, 3) and directrix y = 7. We start by assuming a general point on the parabola (x, y).
Using the distance formula
, we find that the distance between (x, y) is

and the distance between (x, y) and the directrix y = 7 is
.
On the parabola, these distances are equal so, we solve for y:

The answer is 50625 because 5*3 is 15 and take that to the power of 4
