Answer:
7/21
Step-by-step explanation:
M = Y / X
m = [1 - (-2) ] / [2 - (-2)]
m = (1+2) / (2+2)
m = 3 / 4
Using (2,1)
y - yo = m (x-xo)
y - 1 = 3/4 (x-2)
Or
(-2,-2)
y + 2 = 3/4 (x+2)
D and F
The greatest common factor of 8n^3 and 20n is 4n
Answer: 
Step-by-step explanation:
Given
Neville place three weights in the sequence

The total weight of the three weights is

Thus, herbs weigh 
Y = 3x - 1
Slope intercept form is written in this format:
y=mx+b
m represents the slope
b represents the y intercept
You can clearly see that line intercepts the y axis at -1 so if you substitute that in:
y = mx - 1
You can easily find the slope by following this simple formula: rise/run
If you start at (0, -1) and try to get to (1, 2) then you go up 3 units and across 1 unit so the slope is 3/1 or 3. It’s not a negative slope since the line goes upwards and not downwards.
If you substitute the slope and y intercept you get:
y = 3x - 1
