Formula for slope!

Points (p,q) and (r,t) have a slope %28q-t%29%2F%28p-r%29.

If you had slope m, and m=n/d, then for your two points also given, m=n%2Fd=%28q-t%29%2F%28p-r%29.

matrix%281%2C4%2C+Slope%2C+or%2C+%22m%3A%22%2C+%28-+1+-+b%29%2F%28-+3+-+4%29+=+5%2F3%29

%28-+1+-+b%29%2F%28-+7%29+=+5%2F3%29

3(- 1 - b) = - 35 ------- Cross-multiplying

- 3 - 3b = - 35

- 3b = - 35 + 3

- 3b = - 32

b+=+%28-+32%29%2F%28-+3%29 or highlight_green%28b+=+10%262%2F3%29
