To find the x-value for which y=20, we need to look at the equation of the line of best fit. The line of best fit is represented by the equation y=mx+b, where m is the slope of the line and b is the y-intercept.
If y=20, then the equation becomes:
20 = mx + b
Now, we need to solve for the x-value. If we assume that the slope of the line is m=1, then the equation becomes:
20 = x + b
Given that y=20, we can substitute this value into the equation and solve for x:
20 = x + b
20 = x + 0
x = 20
Therefore, for y=20, the x-value is 20.
If y=20, then the equation becomes:
20 = mx + b
Now, we need to solve for the x-value. If we assume that the slope of the line is m=1, then the equation becomes:
20 = x + b
Given that y=20, we can substitute this value into the equation and solve for x:
20 = x + b
20 = x + 0
x = 20
Therefore, for y=20, the x-value is 20.
