May you please help me with this, it is over till midnight 2 ASAP please i beg
This is about scatter plot...my worst enemy please help, please
Question 1 (1 point)
Which equation BEST represents the line of best fit for the scatter plot?
Question 1 options:
y = 2x
y = 2x + 2
y = -2x + 2
y = x + 2
Question 2 (1 point)
Which equation best represents the line of best fit for the scatter plot?
Question 2 options:
y = x + 6
y = 2x + 6
y = -x + 6
y = -2x + 6
Question 3 (1 point)
Which of the linear equations BEST represents the line of best fit for the scatter plot?
Question 3 options:
y = x + 1
y = 2x - 1
Question 4 (1 point)
Which linear equation is the BEST representation of the line of best fit for the scatter plot?
Question 4 options:
y = 3
x = 3
y = -3
x = -3
For question 1 it looks like a straight line through the points would go through y = 2 when x = 0, so the constant term is 2.
The line would increase by 2 units in y for every 1 unit increase in x, so the gradient is 2.
Hence the best fit line would be y = 2x + 2
Try the others using the same reasoning (if the line decreases as x increases the gradient will be negative).
It appears that when y changes by -3, x changes by 3
So the slope is : change in y / change in x = -3/3 = -1
And the y intercept is at 6
So.....using the slope intercept form :
y = -1x + 6 = -x + 6
When y changes by - 1, x changes by 2 → slope = -1/2
And the y intercept appears to be at -1
So the equation is
y = (-1/2)x - 1
Easy!!!....this is a vertical line at x = -3
And that's the equation !!!!
