Answer:
y=mx+b
y=-1x-4
y=2x+4
Step-by-step explanation:
Diameter = 30
30/2 = 15 15 is the radius
To find area:
3.14 x 15 x 15 = 706.5
706.5 is the answer
Answer:
slope = - 
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Rearrange - 9x - 6y = 18 into this form
Add 9x to both sides
- 6y = 9x + 18 ( divide all terms by - 6 )
y = -
x - 3 ← in slope- intercept form
with slope m = - 
I think it would be the second question!
Answer:
i believe it's 31°. not messing around either
