Answer:
y=-x-9
Step-by-step explanation:
y-y1=m(x-x1)
y-0=-1(x-(-9))
y=-1(x+9)
Answer: y + x + 9 = 0
equation of a line with the following values is
y - y1
------- = -1
x - x1
enter the values of the coordinate x1 and y1 into the formula above
y - 0
x - (-9)
x + 9
now cross multiply to have it in a linear form
y - 0 = -1( x + 9 )
y - 0 = -x - 9
y + x = -9
y + x + 9 =0
Hello friend
enjoy your day
t =12 m
We can use similar triangles and proportions to solve this problem.
Put the smaller triangle on top and the larger triangle on bottom
12 9
------ = -------
16 t
Solve by using cross products
12 t = 9*16
12 t =144
Divide by 12
12t/12 = 144/12
t = 12
<u>(1/216)</u> is the right answer.
