We know that the equation of a line is given by
To find it we need the slope m and a point that the line passes thorugh. In this case we have the point (8,10) but we don't know the slope. What we know is that the line we are looking for is parallel to the line
We also know that for two lines to be parallel they have the same slope. Then, if we fin the slope of the line y=2x-5, we have the slope of the line we are looking for. To find the slope of the line y=2x-5 we note that it is written in the slope-intercept form
From this we know that the slope is multiplying the x variable when it is written in that form. Hence m=2.
Then the line we are looking for has an slope of 2 and passes through the point (8,10). Pluggin the values in the equation of a line we have.
Writting it in the slope intercept form we have
Then the line parallel to y=2x-5 and passes through the point (8,10) is
Answer:
Step-by-step explanation:
<u>We know that:</u>
- Slope Formula = y₂ - y₁/x₂ - x₁
<u>Solution:</u>
- y₂ - y₁/x₂ - x₁ = -4 - 4/4 - 4
- => -8/0 = undefined
Since the slope of the line is un-defined, the line is vertical. Please look at my graph to understand better.

Answer:
1. what is a residual?
A. A residual is a value of y -y, which is the difference between an observed value of y and a predicted value of y.
2. The regression line has the property that the_sum of squares_of the residuals is the minimum possible sum.
Step-by-step explanation:
1. What is a residual?
A. A residual is a value of y -y, which is the difference between an observed value of y and a predicted value of y.
2. In what sense is the regression line the straight line that "best" fits the points in a scatterplot?
The regression line has the property that the_sum of squares_of the residuals is the minimum possible sum.
