Since the slope is -2, then m=-2. Since the y-intercept is 5, b=5. Then, we can create the equation: y=-2x+5
Since the slope is  , then m=
, then m= . Since the y-intercept is -3, b=-3.
. Since the y-intercept is -3, b=-3. 
Then, we can create the equation: y= x-3
x-3
 
        
             
        
        
        
Hello,
Slope of the line passing through the points:
m=(12+3)(-3-0)=-5
Slope of the perpendicular: 1/5

Answer:
120 deg
Step-by-step explanation:
There is an angle symbol in the equilateral triangle and another symbol in half of the vertex angle. Those two angles are congruent.
The measure of the vertex angle is 2 * 60 deg = 120 deg
Answer: 120 deg
 
        
             
        
        
        
Answer: y coordinate is 6 
Step-by-step explanation:
6=1/2(3)(h)
If you solve for H then
h=4
So, add 4 to the line y=2
y=2+4
2+4= 6
Hence, the possible y coordinate of point C is 6
Hope this helped! 
I would really appreciate if marked brainlest !
Thank you !
