Here's an example...
So, in our last example...
In the point ( -2, -1 ), x1 = -2 and y1 = -1 ... and, in the point ( 4, 3 ), x2 = 3 and y2 = 3
m = ( y2 - y1 ) / ( x2 - x1 ) = ( 3 - ( -1 ) ) / ( 4 - ( -2 ) ) = 4 / 6 = 2 / 3
But, notice something cool...
The order of the points doesn't matter! Let's switch them and see what we get:
In the point ( 4, 3 ), x1 = 4 and y1 = 3 ... and, in the point ( -2, -1 ), x2 = -2 and y2 = -1
m = ( y2 - y1 ) / ( x2 - x1 ) = ( -1 - 3 ) / ( -2 - 4 ) = -4 / -6 = 2 / 3 ... Same thing!
Let's try our new formula with the second example in the last lesson:
It was a line passing through
( -1, 4 ) and ( 2, -2 )
m = ( y2 - y1 ) / ( x2 - x1 ) = ( -2 - 4 ) / ( 2 - ( -1 ) ) = -6 / 3 = -2

Answer:
$ 175
Step-by-step explanation:
Create an equation:
5000 = ax + 2900
a > 75
x = 12 months
5000 = 12a + 2900
12a = 2100
a = 175
First, u shade in one whole grid which will equal 1 whole. Then, make a another grid and shade in 9 rods and 6 units
Answer:
(a) $7492
(b) $10,253
(c) $14,032
Step-by-step explanation:
As we know, the final Amount can be calculated with the formula for compound interest,
A = P(1 + \frac{r}{n} )^{nt}
where,
A = Final Amount due
P = Initial principal amount borrowed
r = rate of interest in decimal
n = number of times applied per time period
t = total time period
