Yes, the given relationship shown by the data is linear, as the values of x variables vary with a difference of 4 and all the values of y variables vary with a difference of -5.

The slope(m) of for the points
(x_(1),y_(1)) and (x_(2),y_(2)) is given by
((y_(2)-y_(1)) )/((x_(2)-x_(1)))

Slope for points (-9,-2) and (-5,-7) is

=
((-7+2) )/((-5+9))

=
(-5 )/(4)

Equation is given by:
(y-y_(1))= m(x-x_(1))


4y+5x=-53 which is a linear equation.

The model of the given linear equation is attached.
