Answer:
m= 1x or x and b=-2
Graph it and you can find out more
A and B
Reason and proof:
suppose we have the following function
f(x) = 2x + 1
the y intercept is 1 therefor it'll intersect the y axis at (0,1)
however if the function was to be
f(x) = 2x - 1
the y intercept is -1 that means it intersect the y axis at (0,-1)
1. Input:1, output:4
2. Input:1, output:6
3. Input:5, output:8
3. Input:5, output:10
The different between the inputs and outputs are 3, 5, 3, 5. See the pattern?
Hope this helped.
