Alright, to start, slope-intercept form is y=mx+b, where m is the rate is it going up/down by, and b is the starting point.
With this, the question says that Coraz started with 0 naxvips then purchased 10 each month afterwards.
From this, we can fill in the equation, using m as the rate it is going up/down and b as the starting point:
<h3>The Equation: </h3>
y=10x+0
Next, it wants a table, so let's use the equation created to do this. X is the amount of months that have gone by, deciding how many naxvips Coraz has purchased.
So, to start, lets plug in 0 months into the equation into x:
y=10(0)+0
y=0+0
y=0
The answer resulted in 0 for month 0, understandably. Month 0 was when it said Coraz had 0 naxvips on his farms. With this, it would be (0,0) for this part.
For the next month, same thing, just plug it in:
y=10(1)+0
y=10+0
y=10
The answer resulted in 10 for month 1. Month 1 was when it said Coraz purchased his first batch of 10 naxvips. With this, it would be (1,10) for this part.
Again, with 2 months
y=10(2)+0
y=10+0
y=20
The answer resulted in 20 for month 2. Month 2 was when he got another 10 naxvips. With this, it would be (2,10) for this part. However, see the pattern? For every month, there will be 10 more naxvips added. With this, we can write out the table for it as well:
<h3>
The Table:</h3>
(X, Y)
0, 0
1, 10
2, 20
3, 30
4, 40
etc..
which means 12 is the perpendicular & 37 is the hypotenuse [ Since Sin θ =
] . We're asked to find out tan θ ].
. Just plug the values :
