Which equation represents the line that passes through the points (–3, 7) and (9, –1)?

1 answer:

7 0

(y-7) = (-1-7)/(9+3) (x+3)
=> (y-7) = -1/3 (x+3)
=> x+3 = -3y+21
=> x+3y=18
Hope it helps.

Answer:

∠ 1 = 110°, ∠ 2 = 70°

Step-by-step explanation:

∠ 1 and 110° are vertical angles and are congruent, thus

∠ 1 = 110°

∠ 1 and ∠ 2 are same- side interior angles and supplementary, sum to 180°

∠ 1 + ∠ 2 = 180°

110° + ∠ 2 = 180° ( subtract 110° from both sides )

∠ 2 = 70°

Step-by-step explanation:

if u is an irrational number added to a rational number (sqrt 15) to yield 2, then that would mean u would = root -1.78.....

which means you wouldn't have a real solution. if you want a complex answer, it would be sqrt(1.78)i
