Answer:
<em>The answer is Hence Proved</em>
Step-by-step explanation:
        Given that CB║ED ,  CB ≅ ED
        To prove Δ CBF ≅ Δ EDF
         This means that the length of CB is equal to ED 
         As CB║ED The following conditions satisfies when a transversal cut 
         two parallel lines
-     ∠ EDF = ∠ FBC   ( Alternate interior points )
-     ∠ DEF = ∠ FCB   ( Alternate interior points )
        ∴ Δ CBF ≅ Δ EDF    ( By ASA criterion)
         The Δ CBF is congruent to Δ EDF By ASA criterion .
     <em>    Hence proved </em>

Answer:
C)  -3
Step-by-step explanation:
Rearrange your equation so that it is in slope-intercept form (y = mx + b).  The m in the equation is the gradient.
y = 7 - 3x
y = -3x + 7
The m-value is -3.  This means that the gradient is -3.
