If you have 3x + y = 9 write it in slope intercept form... what is the slope, y intercept?
1 answer:
Step-by-step explanation:
given
3x + y = 9
Writing In slope intercept form , y = mx + c
y = -3x + 9
comparing the given equation with y = mx + c
slope (m) = - 3
y-intercept (c) = 9
Hope it will help :)

Minus 9x from both sides
-3y=-9x+12
divide both sides by -3
y=3x-4

x-4>4
x>4+4
x>8
Answer:
Finding b:
57+b = 180 (linear pair)
b = 123
Finding c:
c = 123 (vertical angles are always congruent
Recall that (a+b)²=a²+2ab+b²
100x²+120x+z
in this case, because100x²=(10x)², a=10x, z=b²
120=2*10*b
b=6
z=b²=36
the square is (10x+6)²
