Answer:
y=-2x+160
Step by Step:
The equation of a line can be determined using the point slope formula:
y-y1=m (x-x1)
To make a substitution, we must ensure we have the correct information. The question gives:
y1=60
x1=50
y=1/2x+10 This is the formula of a line that is perpendicular to the one we are trying to find.
It tells us that the gradient of the perpendicular line is 1/2. The gradient of the line we are trying to find can be found using m1×m2=-1 because we know that when lines are perpendicular, the product of their gradients must equal 1
So if we replace m1 with 1/2
1/2×m2=-1
m2=-2
We now have all the relevant information to make a substitution:
y-60=-2 (x-50)
expand brackets
y-60=-2x+100
rearrange to get in the form y=mx+b
y=-2x+160

Answer:
The correct answer is m=
and θ = 30º.
Step-by-step explanation:
First, we must form a triangle whose hypotenuse is the radius r=1, its adjacent leg is m, its opposite leg is 
and the angle is theta.
First, we calculate the angle with theta's breast:
sin (θ) = 
where H is the hypotenuse, in this case, the radio.
θ = 
(
)
θ = 30º
Now, we calculate the adjacent leg, which is equal to the x-coordinate of the point:
cos (θ) = 
m = cos 30º * H
m = 
m =
