Use the point-slope form of an equation of a line.
 )
where )
are the coordinates of the given point and 
is the given slope.
By the way, "-2, 9" does NOT describe a point in 
, (-2, 9) describes a point in .

A line passes through the point -2, 9 and has a slope of -3. Write an equation for this line
.
plug given info into "point-slope" form:
y - y1 = m(x - x1)
y - 9 = -3(x - (-2))
y - 9 = -3(x + 2)
y - 9 = -3x - 6
y = -3x + 3 (this is what they're looking for)
