Let's start with y=mx+by=mx+b

Explanation:

Use what we know:
7=6*m+b->7=6m+b

Now we express bb in terms of mm:
b=7-6m->y=mx+7-6m->y=m(x-6)+7b=76my=mx+76my=m(x6)+7

An other way:
From the "simple" function y=mxy=mx, that passes (0,0)(0,0) we have translated 66 to the right, which makes for the -66, and 77 upward, which makes for the +7+7

x=6.

Explanation:

We first observe that the slope of the required line = m is undefined. This means that the reqd. line must be vertical line & as, by data, it passes through the point (6,7), its eqn. must be x=6.
