Using coordinates of the labeled points to find a point slope equation of the line

y +4= -3 ( x-3)

Step-by-step explanation:

The point slope form of a line is

y-y1 = m(x-x1)

The point requested is (3,-4)

y - -4= m ( x-3)

y +4= m ( x-3)

The slope of the line  is positive since it goes from the top left to the bottom right

The slope can be found from (0,5) and (3,-4)

m = (y2-y1)/(x2-x1)

    = (5 - -4)/(0-3)

    = (5+4)/(0-3)

    = 9/-3

    = -3

y +4= -3 ( x-3)

The slope in all answer choices is 3 or -3.

Since the line is going down, the slope is going to be negative (-3).

Point slope form: y - y1 = m(x - x2)

We are given a point in the question so use it to fill in the equation.

y + 4 = -3(x - 3)

Best of Luck!

step-by-step explanation:

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
