or

Explanation:

Point slope form is essentially:

y

−

y

1

=

m

(

x

−

x

1

)

y

1

and

x

1

are coordinates given to you. They can either be 6 and 4 respectively, or 7 and 5 respectively. Pick your choice.

m

=

y

2

−

y

1

x

2

−

x

1

So, plug in coordinates for that.

Remember, the plain ol' y and x in the point slope form equation will be the actual variables, since functions need those guys to stick around.
