Answer:
x = 
y²
Step-by-step explanation:
Any point (x, y ) on the parabola is equidistant from the focus and the directrix
Using the distance formula, then
= | x + 3 |
Squaring both sides
(x - 3)² + y² = (x + 3)² ← expanding both sides
x² - 6x + 9 + y² = x² + 6x + 9 ← subtract x² + 6x + 9 from both sides
- 12x + y² = 0 ( subtract y² from both sides )
- 12x = - y² ( divide both sides by - 12 )
x = y²
Exponents are numbers that are compressed. These numbers are simplified by finding a number that when multiplied by itself multiple times will get to the original number.
This sequence can be rewritten as:
10⁻¹; 10¹; 10²; 10³; 10⁴

Step-by-step explanation:
Answer:
-1/2
Step-by-step explanation:
The slope of a line is found by using
m = (y2-y1)/(x2-x1)
= (9-10)/(6-4)
= -1/2
