Question 252468
step 1 - find the original slope. We need to use the slope formula
m = {{{Y2-Y1}}} / {{{X2-X1}}}.
put your coordinates into the formula, remember coordinates are (X,Y)
m = {{{0-4}}} / {{{-1-2}}}
m = -4/-3 = 4/3
step 2 - we want the perpendicular slope. so we take the original slope and apply a negative flip. 4/3 - -> -3/4.
This is answer choice [ B ].
