Lines a and b are perpendicular. The equation of line a is y=1/3x+3. What is the equation of line b
kykrilka [37]
Perpendicular lines have slopes that are negative reciprocals to each other, that is, if one slope is a/b, the other is -b/a
in this case, the given slope is 1/3, so the other line's slope is -3/1, which is -3
from the graph we see that the y intercept of line b is -4, so the equation of line b is: y=-3x-4

Please help me with this!!!!!
Orlov [11]

Answer:

C. ΔJKL, in which m∠J = 15° and m∠L = 45°

Step-by-step explanation:

To solve, let's find the missing angle of the triangle:

180 - 120 - 15 = 45°

That means a solution should have at least 2 solutions from the solution set (15 , 45, 120)

C, is the correct choice.

If my answer is incorrect, pls correct me!
