Y = -2x + 3
Slope is -2......and when x = 0 thats the y intercept.
To calculate the standard deviation of those numbers:<span>
1
Work out the Mean (the simple average of the numbers)
2
Then for each number: subtract the Mean and square the result.
Then work out the mean of those squared differences.<span>Take the square root of that and we are done!</span></span>

Answer:
X= - 44
18x+3x+4-5=5(4x9
Collect like terms
21x+4-5=5(4x-9
More variable to the left hand side and change its sign
21x-20x-1=-45
Correct like terms
X=-45+1
Which is x=-44
