(5,1)(-3,4)
slope = (4 - 1) / (-3 - 5) = -3/8
y - y1 = m(x - x1)
slope(m) = -3/8
(5,1)...x1 = 5 and y1 = 1
now we sub
y - 1 = -3/8(x - 5) <=== point slope form
y - 1 = -3/8(x - 5)
y - 1 = -3/8x + 15/8
y = -3/8x + 15/8 + 1
y = -3/8x + 15/8 + 8/8
y = -3/8x + 23/8 <=== slope intercept form
y = -3/8x + 23/8
3/8x + y = 23/8 ...multiply everything by 8
3x + 8y = 23 <==== standard form
None of those answers work. The correct answer should be (9/22).
Answer:
x ≈ 61.8
Step-by-step explanation:
Using the sine ratio in the right triangle
sin15° =
=
( multiply both sides by x )
x × sin15° = 16 ( divide both sides by sin15° )
x =
≈ 61.8 ( to the nearest tenth )
