Question

find the slope intercept form of an equation of a line passing thru (2,3) and
a) parallel to y= -3x+2
b) perpendicular to y=-3x+2

plz help,... im effin stuck someone smart

Answer 1

parallel means slope is the same, so use
\[y-y_1=m(x-x_1)\] with
\[x_1=2, y_1=3, m =-3\]

Answer 2

get
\[y-3=-3(x-2)\]
\[y-3=-3x+6\]
\[y=-3x+9\] for the first one. second one is similar, but this time slope is
\[\frac{1}{3}\]
