Answer:
y = 6x + 9
Step-by-step explanation:
Δy =-3-3 = -6
Δx =-2-(-1) = -1
Slope = Δy/Δx = 6
Point-slope equation for line of slope 6 that passes through (-1,3):
y-3 = 6(x+1)
Rearrange to solve for y:
y = 6x + 9
1. Find angle Y. Since the interior angles of a triangle must add up to 180 deg., we have 180 - (98+24) = 58 deg.
Apply the Law of Sines to determine the lengths of sides r and t:
r 7.9 t
--------- = --------- = ---------
sin 98 sin 58 sin 24
Then r = (7.9 sin 98)/ (sin 58) = 9.22. This matches r in the 2nd choice. Determine t using the same method: t = 7.9sin 24 / sin 58.
Does your t value match that in the 2nd possible answer?
