Answer:
slope form = y= 3/4x -7
point slope= y-(-3) = 3/4(x-3) or y-(-4)= 3/4(x-4)
Step-by-step explanation:
slope form = y= mx + b
y = 3/4x - 7
point-slope form = y - y1 = m(x - x1)
step 1. Substitute a convenient value of x into your equation and solve for y (You're doing this to get the point x1,y1). Let's choose x=3. Yes, you could choose x=4.
y= 3/4x - 7
if you choose x = 3
y=3/4(3) - 7
y = 4 -7
y = -3
(x1,y1) = (3,-3)
if you choose x = 4l
y= 3/4(4) - 7
y = 3 - 7
y = -4
(x1,y1)= (4, -4)
step 2. Substitute the point you found , (x1, y1) , into the point slope formula.
if you choose x=3
y-y1=m(x-x1)
y-(-3) = 3/4(x- 3)
if you choose x = 4
y- y1 = m(x-x1)
y - (-4) = 3/4(x-4)

Answer:
- length: 8
- end points: (-8, 1), (0, 1)
Step-by-step explanation:
In the quadratic form ...
(x -h)² = 4p(y -k)
The value 4p is the length of the latus rectum. It also tells the distance between the vertex (h, k) and the focus (h, k+p).
<h3>Application</h3>
The value of 4p is given as 8. This means p = 8/4 = 2.
The length of the latus rectum is 8.
The end points of the latus rectum have the same y-value as the focus:
y = k +p = -1 +2 = 1
The end points of the latus rectum have x-values that are h±2p.
x = h ± 2p = -4 ± 2·2 = {-8, 0}
The end points of the latus rectum are (-8, 1) and (0, 1).
8 is the largest number that goes into both 32 and 40.
40/8 = 5
32/8 = 4
so there can be 8 teams, each consisting of 5 girls and 4 boys
5 x 3 = 15
3 3\5
The answer is 3 3\5
