Question

Show how u find (M) SlopeShow how you find (B) y-interceptWrite function(equation) in form of y=mx+b

Answer 1

If we analyze the first case we have this:

Lets select the points (-1,5) and (0,8)

The slope is given by:

`m=(8-5)/(0+1)=3`

And we can find the intercept in the following way:

5= 3(-1) +b

b= 5+3=8

Then the equation would be:

y= 3x +8

For the second case we can select (13,7) and (14,8) and we got:

`m=(8-7)/(14-13)=1`

And the intercept would be:

7 = 1*13 +b

b= 7-13= -6

Then the equation would be:

y= x -6
