Answer:
Step-by-step explanation:
90 degrees
x + y = 180
x = y
x + x = 180
2x = 180
x = 180/2
x = 90
Both the angle and its supplement = 90

Answer:
you have to have a value for B and D
Step-by-step explanation:
Answer: slope intercept is y=mx+b form s b= the y intercept and x will just be x and the m is usually a fraction which tells you the slope so what you need to do is mark these points on a line graph draw a line from one to the other and every where it crosses over a point is where you can find the slope and the y intercept giving you the answer
