Answer:
D) (0,9.5) and (10,1.5)
Step-by-step explanation:
a line of best fit is a line that is drawn through the data points on the scatter plot. Option D is the only answer that draws a linear line through the data points.
Option A makes a short line above the points. if the line is not through the points, it doesn't work
Option B is drawing a positive line (as in it's increasing) and therefore cannot work
Option C draws a line below the points and does not represent the line of best fit for this scatter plot
Answer:
7.5
Step-by-step explanation:
Answer:
For x = 10, the lines will be parallel
Step-by-step explanation:
<em><u>For parallel lines in a triangle, their sides must be proportional</u></em>
And,

<em>Cross Multiplying</em>
=> x(x+4) = (x-3)(x+10)
=> 
=> 
=> 3x = 30
<em>Dividing both sides by 3</em>
=> x = 10
