Find the value of y so that the line passing through the two points has the given slope?
1. (12,y), (-6,9/7), m= -1/6
write an equation in slope-intercept form. (then graph the equation).

The point (-6,9/7) must be on that line: use it to find c by plugging in x and y like
So what's c?
So now we have the equation of the line, we need the value of the point on that line where x=12. Plug in 12 instead of x in the equation and work out what y must be.
we need to write as y=mx+c
move everything but y to the RHS:
which you can simplify a bit.
You can do the other yourself the same way.
