Answer:
y intercept = 3
--- slope
Step-by-step explanation:
Given
The attached graph
Required
Determine the slope and the y intercept
The 
is at the point where 
.
From the graph:
Hence,
y intercept = 3
Next, we calculate the slope using:
Where:
So, we have:
Answer:
y=25x-500
Step-by-step explanation:
25 is positive with the x because its the slope and 500 is the cost so you subtract is. 500 is the y intercept
Answer:
x=0
y=7
Step-by-step explanation:
Divide 6x-4y=-28 by -2..... -3x+2y=14
3x+5y=35
-3x+2y=14
--------------
7y=49
y=7
6x-4*7=-28
x=0
Ratio is a way of comparing two numbers which are of the same kind. It is normally expressed by separating two numbers with a colon(:) or you could also use division sign (/). The only way that ratios can have mean is that both number should be non-zeros and both of them should have the same sign. Thus having this in mind, the ratio of the numbers above will be:
(1357k)/(298k)
=1357:298
Answer:
-0.125
