We say that d is a common factor of a and b if d is a factor of both a and b. We say that d is the highest common factor of a and b if there is no other factor of both a and b that is greater than d. Notation: HCF(a,b) = “highest common factor of a and b” .
The slope will be -3/4 To find slope you just place the change in y over the change in x. 2- -1=3 0-4= -4 The slope is -3/4 which is the same as before
