I think it’s the first one. 30:54 because 5 times 6 is 30 and 9 times 6 is 54.
Y=5 it's a horizontal lines so b in y=mx+b would have to be 5 and since it's horizonal, it doesn't have a slope so it's just y=5
Answer: number 2
cuz its the only one that makes sense
Answer:
m:
Step-by-step explanation:
Pick two points (0,5) and (3,4)
use the formula to find slope: 
Insert values: 
m:
:-)
Answer:
(a)
and 
Step-by-step explanation:
Required
Which of a to d has no solution
(a)
and 
We have: 
Sole for m



Divide by 6

So, we have:
and 
implies that: m = -6,-7,-8,-9.....
implies that m = -3,-2,-1,0.....
<em>Hence, there is no solution</em>
