Answer:
y = -2x + 1.
Step-by-step explanation:
2y = x - 1
y = 1/2y - 1/2
If line X is perpendicular to line Y (the line where y = 1/2y - 1/2), the slope will be the negative reciprocal of line Y. That means that there will be a negative sign instead of positive, and the 1/2 will be flipped to become 2/1, which is 2.
So, the slope will be -2.
We now have y = -2x + c.
To find c, simply put in -1 for x and 3 for y.
3 = -2 * -1 + c
c + 2 * 1 = 3
c + 2 = 3
c = 1
So, the equation of the line is y = -2x + 1.
Hope this helps!

Answer:
-1 1/2
Step-by-step explanation:
-(3-6b)=6b + 5 .remember to balance!!!!
-6b + 6b= 6b + 6b
-3=12b+5
-3+5=5-5
-8=12b now divide since its the inverse operation
think 12/-8= -1 1/2
so B equals - 1 1/2
Answer:
B
Step-by-step explanation:
b is correct
'what number' indicates an unknown value we can represent with 'x'
'is' indicates an equal sign.
25% = 0.25
'of' indicates multiplication.
x = 0.25 * 180
x = 45
