Jacob drew a regression line for this paired data set his line passed through (2,10) and (7,18) what is the equation of jacobs regression line? a)y=6.8x+1.6 b)y=1.375x+4.25 c)y=0.625x-4.25 d)y=1.6+6.8

Step-by-step explanation:

1. The equation of a regression line has the following form:

Where is the slope and is the y-intercept.

2. You need to calculate the slope with the points given in the exercise:

3. Substitute values:

4. Now, you must calculate :

-Substitute the value of the slope into the equation above.

- Take one of the given points and substitute them into the equation.

Then:

5. Therefore, the equation is:

the correct answer is you spend $55.78 more in a brand store that buy ing in a normal store.

step-by-step explanation:

brand = spend   $ 135.85 total

store = spend $80.07 total

on a coordinate grid, point a is at (−4.0, −2.4) and point b is at (4.0, −2.4). point b is a reflection of point a across the –axis. input either a lowercase x or i think is the right awnser
