Identify an equation in point-slope form for the line perpendicular to
y=-4x - 1 that passes through (-2,7).
o a. y-7 - -4(x +2)
o b. y+2- (x-7)
o c. y+7 -- (x-2)
o d. y-7 - 3(x+2)
submit

A. y - 7 = -4(x + 2)

Step-by-step explanation:

Insert the coordinates into the formula with their CORRECT signs. Remember, in the Point-Slope Formula, y - y₁ = m(x - x₁), all the negative symbols give the OPPOSITE term of what they really are. In addition, I recall that perpendicular lines have OPPOSITE MULTIPLICATIVE INVERSE [RECIPROCAL] rate of changes [slopes], so -4 really should be replaced with ¼, but if your assignment says otherwise, then this is the answer.
