Question

Choose the equation of the line passing through the point (-1, -2)and perpendicular to y = 1/4x + 2


y = -4x - 6
y = 4x
y = 4x - 6
y = -4x + 2

Answer 1

the slope of your given line is m = 1/4 the slope of the perpendicular is the negative reciprocal of the given slope.... so slope of the perpendicular is m = -4

the line equation is y = -4x + b

substitute x = -1 and y = -2 to find the value of b, the y-intercept.

then you have the equation of the line.
