(-6,4) and (3, 1)
slope =(4-1)/(-6-3) = -3/9 = -1/3
equations
y - 4 = -1/3(x + 6)
y - 1 = -1/3(x - 3)
answer C and F
C. y - 1 = -1/3(x - 3)
F. y - 4 = -1/3(x + 6)

Answer:
B
Step-by-step explanation:
You need to find x, so you'll have to use cos in this case, because x is adjacent to the only angle you have.
So, you'll get:
cos 30 = x/10 (adjacent/hypotenuse)
Rearrange the equation for x:
x = cos 30 x 10
<em>*Since the options you have are in exact values, you can't use a calculator just to find x. </em>
Cos 30 in exact values is √3/2
<em>*you can either memorise these values or learn the trig triangles. either way, just know the exact values for sin, cos and tan for 30, 60 and 90 degrees</em>
So to find x:
x = √3/2 x 10
x = 5√3
