The equation of the line is 
Step-by-step explanation:
The slope is 
Also, the line passes through the points 
To find a line with slope
that passes through the points
, let us use the equation of a line with slope that passes through the point is given by
where m is the slope and
are the points
.
Thus, substituting the values in the equation of a line, we get,

Multiplying the term
by -5, we get,

Adding both sides by 5x,

Subtracting 35 from both sides of the equation,

Thus, the equation of the line is 
-6≤ w ≤ 2 is the answer. Hope this helps!
