Poloma believes that the equation of the line of best fit for the following scatterplot is y = 5/6x - 31/6. Which statement best summarizes why she must be wrong?

Poloma’s equation has a positive y-intercept, but the scatterplot has a negative correlation.
Poloma’s equation has a positive slope, but the scatterplot has a negative correlation.
Poloma’s equation has a negative y-intercept, but the scatterplot has a positive correlation.
Poloma’s equation has a negative slope, but the scatterplot has a positive correlation.

\3. yes the presentation (i.e. odd numbers being written as differences of two squares) is possible for all odd natural number however the presentation may not be unique. for example,  57=112−82=292−28257=112−82=292−282.

\4. 2 can't be written as a difference of two squares because 4-1=3 and 1-1=0 and the difference of squares grows to integers larger that 3.

can i get some in proving questions 1 and 2?

the equation of the line that passes through the points and has o form

if line passes through the points (-1, -3) and (2, 1), then

the equation in the standard form is
