Triangle ABC is similar to triangle CEF.
<u>Explanation:</u>
<u></u>
Diagram is inserted for the reference.
ABCD is a rectangle.
ABC is a right angled triangle because all the angles of the rectangle are 90◦ - (a)
CEF is a right angled triangle because FE is perpendicular to DC – (b)
In triangles ABC and CEF,
1. Angle ABC = Angle CEF = 90◦ (Both are right angles from a and b)
2. Angle BCA = Angle EFC (Alternate angles on parallel lines are equal on intersection)
Hence using Similarity property of AA (Angle, Angle), Triangle ABC and CEF are similar.
<u></u>
Parallel lines will always have the same SLOPE. In the case of this equation, the slope is 
since 
is the same as 
and the coefficient of is the slope. Because there is no 
, the graph of the equation will NEVER intercept the y-axis. Therefore, whatever answer option does not have is correct.
