The vertex is exactly half way between directrix and focus. In this case the vertex is (8,-7)
(h,k)
P is the distance between the vertex and either the directrix or focus, in this case p = 1.
a = 1/(4p) or 1/(4*1) or 1/4
write the equation in vertex form
y = a(x-h)^2 + k
y = 1/4(x-8)^2 -7

Answer:
Answer: 042
Step-by-step explanation:
The fourth clue eliminates 7, 3 and 8 as possibilities, the fifth clue means that 0 is the correct number but in the wrong position. The third clue indicates that the right digits, including the 0, are in the wrong place. That means the 0 must be the first number of the code.
Based on the first and second clues, the 6 must be eliminated as a possibility because it’s in the same place in both clues, but one clue says it’s in the right place and the other clue says it’s in the wrong place. So by looking at the first clue, we can determine that 6 and 8 are both eliminated (the 8 due to the fourth clue), meaning that the 2 is right and in its place.
The final number can be solved using the second clue. Because the digit remaining to be solved is the second digit, the answer must be 4 and not 1. The digit is right but in the wrong place, so it can’t be 1, which is already in the middle, so it must be 4, meaning the full answer is 042.
Answer:
1) Slope of the line 
2)Slope of the line m = 2
3) slope of the line m = -5
Step-by-step explanation:
<u><em>Step(i):-</em></u>
Given that equation of the straight line 3 x+2 y =0
The slope - intercept form y = mx +c
2 y = - 3x
Slope of the line 
<u><em>Step(ii):-</em></u>
Given that equation of the straight line 2 x- y = 3
The slope - intercept form y = mx +c
y = 2x -3
slope of the line m = 2
<u><em>Step(iii):-</em></u>
Given that equation of the straight line 5 x + y = 10
The slope - intercept form y = mx +c
y = -5x +10
slope of the line m = -5
