Answer/Step-by-step explanation:
Use equation y = mx+b
m is the slope and in the place for m is 15
b is the y intercept and because there is no y-int. it would be 0
Since the y-int is 0 then it is proportional.
This would be a positive slope.
Hope this helps :)
Answer:
M = -4/3. B = 8
Neg slope
non-proportional
Step-by-step explanation:
so yes its is a solution
well plug in 4 on both side and see if its the same on both sides
2x4+12 = 20
3x4+8= 20
20 = 20
Answer:f(4)=1/2
f(x)=4 when x is 8
y=2
x=3
