Answer:
y = 15x
Step-by-step explanation:
Given x and y are in direct variation then the equation relating them is
y = kx ← k is the constant of variation
To find k use the condition x = 2, y = 30, then
30 = 2k ( divide both sides by 2 )
15 = k
y = 15x ← equation of variation
If m(slope)=3, you can start to set up the equation as y=3x+b.
Using y=3x+8, you can plug in the given point being (8,5).
y=5
x=8
5=(3*8)+b
5=24+b
b=-19
The equation would be y=3x-19
