Question 238381
we parents have to stick together...


1) the general point-slope form is ___ y minus "y-coordinate" equals slope times (x minus "x-coordinate")
___ in this case ___ y - 0 = -3 (x - 8) ___ or y = -3x + 24



2) for the lines to be parallel, the slopes must have the same value
___ in this case, the left side of the equation stays the same
___ use the given point to find a new value for the right side
___ 3(-1) - (0) = -3
___ so the new equation is ___ 3x - y = -3
