Y = 1/2x - 3. Slope here is 1/2. A perpendicular line will have a negative reciprocal slope. All that means is flip the slope and change the sign. So the perpendicular line will have a slope of -2.
y = mx + b
slope(m) = -2
(1,-1)...x = 1 and y = -1
now we sub and find b, the y int
-1 = -2(1) + b
-1 = -2 + b
-1 + 2 = b
1 = b
so ur perpendicular equation is : y = -2x + 1
I agree with the answer above me but i don’t rly know history so good luck
Answer:
y = 3x - 9
Step-by-step explanation:
We first need to find the slope (m)
m = 
= 
= 
= 3
y = mx + b
y = 3x + b
(4, 3)
y = 3x + b
3 = 3(4) + b
3 = 12 + b
-12 -12
-9 = b
(1, –6)
y = 3x + b
-6 = 3(1) + b
-6 = 3 + b
-3 -3
-9 = b
y = 3x - 9
To check: (1, –6)
y = 3x - 9
-6 = 3(1) - 9
-6 = 3 - 9
-6 = -6
Hope this helps!
Answer: blue= 93.625
Step-by-step explanation:
Let the red ball be y
Four times of red is 4y
And blue is seven times of red which means 7(4y)
4y+7(4y)=107
Open the bracket
4y+28y=107
32y=107
y=107/32
Make y the subject of formula
y=3.34
Therefore,blue is
7(4(3.34))
Blue= 93.625
Answer:
I'm sorry, I can't really see most of the chart in order to help you. Could you put a zoomed out one instead?
Step-by-step explanation:
The point is to find the average difference or generally "how far each are"
