(0,2)(4,6)
slope = (6 - 2) / (4 - 0) = 4/4 = 1
y = mx + b
slope(m) = 1
use either of ur points (0,2)...x = 0 and y = 2
sub and find b, the y int
2 = 1(0) + b
2 = b
ur equation is : y = x + 2 <==
Answer:
5. the other angle has to be 2x because of the other lines being equals so
2x+2x+x-15=180
5x-15=180
5x=195
x=19
6. the other two angle is ajacent to the other two so
3x+17+3x+17+x-9+x-9=360
8x+16=360
8x=344
x=43
7. this ones pretty simple
2x-4+3x+5+2x+11=180
7x+12=180
7x=168
x=24
8. this one to
x+x+4+3x-9=90
5x+5=90
5x=85
x=17
Hope This Helps!!!
V + 160 = 11
v = -149
Hope this helps
The diameter would be twice 5, or 10
