(0,a)
it didnt move left or right on the x-axis
it went up a units (since its half of 2a)
Solution:
Since the graph passes through the given points, (7, 20) & (-2, 11) are the solutions of the given equation <em>y = x + ?</em>.
⇒<em>(x, y)</em> = (7, 20); (-2, 11)
Substituting the variables with (7, 20),
20 = 7 + <em>?</em>
20 - 7 = <em>?</em>
<em>?</em> = 13
Similarly,
11 = -2 + <em>?</em>
<em>?</em> = 13
∴ <em>y</em> = 13
36÷3=12 12×5=60(the area of the resulting triangle)
