What is an equation of the line that passes through the point (-1,-3)(−1,−3) and is perpendicular to the line x-2y=14?

its 60

4 x 12 = 48

3 x 4 = 12

48 + 12 = 60

yeeeet

yx = 36

step-by-step explanation:

cos f = opposite side/ hypotenuse

cos f = yw / yx

we know cos f = 4/9 and yw =16

4/9 = 16/yx

multiply each side by yx

4/9 yx = 16/ yx * yx

4/9 yx = 16

multiply each side by 9/4

9/4 * 4/9 yx = 16 *9/4

yx = 36

is the anwser b. (-13)?
