Answer
Y=1/2x-3
Explanation
The general equation of a straight line is the form
Y = mx + c
where m ⇒slope of the line.
In the equation given, we make y the subject of the formula then we arrange the equation to resemble y=mx+c.
6y-3x=-18
6y = -18 + 3x
y = -18/6 + 3x/6
-3 + (1/2)x
y = (1/2)x - 3
12^2 + 5^ = c^2
144 + 25 = c^2
169 = c^2
13=c
1. If a and b vary inversely and b = 8 when a = 6:
b = k/ a
8 = k / 6
k = 6 * 8
k = 48
Function is:
b = 48 / a
2. When a = 30:
b = 48 / 30 = 8/5
b = 1.6
