Find the standard form of the equation of the parabola with a focus at (-4, 0) and a directrix at x = 4.
Answer:
csc π.
Step-by-step explanation:
csc π because csc = hypotenuse / opposite side and the opposite side = 0. Anything divided by zero is undefined.
Another way to the same conclusion is: we know that sin π = 0 and csc π = 1 / sin π = 1 / 0 which is indeterminate.
Answer:
y - x= - 13 -------(1)
- 4x + 3y = -51 -------(2)
(1) => y = - 13 + x
Substitute y in (2)
- 4x + 3( - 13 + x) = -51
- 4x - 39 + 3x = -51
- x = -51 + 39
- x = -12
x = 12
Substitute x in (1)
y = - 13 + x = -13 + 12 = - 1
x = 12, y = -1
Hey there Hopire :)
To solve this, we'll use the slope given two points formula. Here it is:
y2-y1/x2-x1
Plug in the values.
6-2/9-7 =
4/2 =
2
Therefore, the slope is two, meaning 2/1 because slope is rise/run. That means that for every two you go up, you go one to the right because it's a positive slope- left for negatives.
Hope this helped!

When x = 0, y = 1.5 * 0 = 0
