Answer:
1/2
Step-by-step explanation:
Pick two points on the line
(0,-4) and (2,-3)
Using the slope formula
m = (y2-y1)/(x2-x1)
= (-3 - -4)/(2 -0)
(-3+4)/(2-0)
1/2

Answer:
c = 9 feet
Step-by-step explanation:
In this situation, one is to find the 'c' : that is, the distance between the vertex and the focus.
Given that, the equation for a vertical parabola:
y = (1/4c)(x-h)^2 + k
Supposing we place our parabola at the center, our equation becomes:
y = (1/4c)x^2
.
The problem gives us a point on the parabola: (12,4)
Then insert it in and solve for 'c':
y = (1/4c)x^2
4 = (1/4c)12^2
4 = (1/4c)144
4 = (1/c)36
4c = 36
c = 36/4
c = 9 feet
Answer:
y = 3m - 6
Step-by-step explanation:
y = mx + b
b is the point where the line cuts the y axis.
That happens at (0,-6)
So far what you have on this equation is
y = mx - 6
You could use the point that cuts the x axis to find m.
y = 0
x = 2
0 = m*2 - 6 Add 6 to both sides
6 = m*2 - 6 + 6
6 = 2*m Divide by 2
6/2 = 2m/2 Do the division
3 = m
Answer
y = 3m - 6
