Write the equation of the line that passes through the point (-4,-2) and is parallel to the line y= 1/4x + 3

First find the gradient of the perpendicular line. You do this by taking the negative reciprocal of the gradient of the first line (y= 1/4x +3):

Perpendicular gradient = negative reciprocal of = -4

Next, you substitute the x and y values into the following equation and solve:

y = -4x +c

-2 = -4(-4) +c

-2 = 16 + c

-18 = c

Substitute c back into the equation above to get the final

y = -4x -18

-------------------------------------------------

Answer

y = -4x - 18

the answer is b.

step-by-step explanation:

by the trigonometric ratio tangent, tangent equals opposite divided by adjacent.

therefore, tan(50) equals ac/3

multiply each side by 3 to get: ac=3tan(50)

the answer is b.
