The equation in slope intercept form is
y=-(3)/(2) x-3

Step-by-step explanation:

The given pair of points are
(2,-6) and
(-4,3)

The slope can be determined using the formula,


m=(y_(2)-y_(1))/(x_(2)-x_(1))

Substituting the points
(2,-6) and
(-4,3) in the slope formula, we have,


m=(3+6)/(-4-2)


m=(9)/(-6)


m=-(3)/(2)

The equation in slope intercept form can be determined using the formula,


y-y_1=m(x-x_1)

Substituting
m=-(3)/(2) and the point
(2,-6) in the above formula, we get,


y+6=-(3)/(2) (x-2)


y+6=-(3)/(2) x+3


y=-(3)/(2) x+3-6


y=-(3)/(2) x-3

Thus, the equation in slope intercept form is
y=-(3)/(2) x-3
