k = 
and b = 
Given 2 points that lie on the graph of y = kx + b then the coordinates of these points will make the equation true. Substituting the coordinates into the equation allows us to find k and b
(2, 10) → 10 = 2k + b → (1)
( - 7, - 10) → - 10 = - 7k + b → (2)
subtracting (2) from (1) term by term gives
(10 - (- 10)) = (2k - (- 7k)) + (b - b)
20 = 9k → ( divide both sides by 9)
k =
Substitute this value into ( 1) or (2) and solve for b
(1) → 10 = (2 × ) + b
hence b =

The line y = 12 is a horizontal line with a slope of 0.
Therefore a line parallel to line y = 12 will have a slope of 0.
A line perpendicular to line y = 12 is a vertical line, the slope of a vertical line is undefined.
Based on the fact that the Polygon ABCD was translated, then the polygon that is a translation of it will be Polygon 3.
<h3>What polygon is the translation of Polygon ABCD?</h3>
When a shape is translated, it is taken as it is from one area of the coordinate plane, to another area of the plane.
This means that it doesn't change in height, or orientation.
The only polygon that still looks like Polygon ABCD is Polygon 3 which means that it is the translated version.
