PLEASE HELP ME I WILL MARK BRAINLIST!!!!

Mathematics
1 answer:
elixir [45]3 years ago
5 0

Answer: A

Step-by-step explanation: The slope of perpendicular lines is opposite reciprocal. In this case the slope would be 4/3. Plug in for x and y, you get -7 for b.

  • y = mx +b
  • 9 = 4/3 (12) + b
  • 9 = 16 + b
  • -7 = b

Rewrite the equation --> y = 4/3x - 7

Twice the complement of angles A is 40 less than the supplement of angle A. Find the measure of angle A
Serggg [28]
Complement adds to 90
complement of A is 90-A


supplement is adds to 180
supplemetn of A is 180-A

2(90-A) is -40+180-A

2(90-A)=-40+180-A
2(90-A)=140-A
distribute
180-2A=140-A
add 2A to both sides
180=140+A
minus 140 both sides
40=A

A=40 degres

What is the equation of the line that passes through (4, -1) and (-2, 3)?
inessss [21]
(4,-1),(-2,3)
slope = (3 - (-1) / (-2 - 4) = -4/6 = -2/3

y = mx + b
slope(m) = -2/3
use either of ur points...(4,-1)...x = 4 and y = -1
now sub into the formula and find b, the y int
-1 = -2/3(4) + b
-1 = -8/3 + b
-1 + 8/3 = b
-3/3 + 8/3 = b
5/3 = b
so ur equation is : y = -2/3x + 5/3
