Chapter 6

Now we know what m is, we can put that in our equation to find y.

y=mx+b

Remember the m is the slope or gradient and the b is the y intercept.

The m will be 4/7 and the b will be 1.

y=4/7x+1

We put the results in a table:

Here's how we got the y using the equation:

y=mx+b

=4/7x+1

= 4/7(1)+1 (you multiply 4/7 by 1)

=4/7+1 (you add 1 to 4/7)

=1 4/7

y=mx+b

=4/7x+1

=4/7(2)+1

=8/7=1 (simplify 8/7 to 1 1/7)

=1 1/7+1

=2 1/7

We also did a problem where b=0.

Since b=0, then in the equation there doesn't need to be +b. We used 1 and 14 for x.

y=mx

=2/3x

=2/3(1)

=2/3

y=mx

=2/3x

=2/3(14)

=28/3 (simplify 28/3 to 9 1/3)

=9 1/3

Great post Glenesse. Your detailed information really explained a lot from the picture. Also the way of explaining the rise and run. Next time maybe you can add a video or a link to have further information.
