There are no steps to show, you just have to know which part of the equation effects which part of the graph:
Eqn. 5 matches b (since there were absolutely no translations)
Eqn. 6 matches d (since there was a vertical translation of one upwards)
Eqn. 7 matches a (since there was a horizontal translation of one to the right)
Eqn. 8 matches c (since there was a reflection upon the y-axis and a vertical translation of two downwards)
Step-by-step explanation:
<u>Statement Reason </u>
BA and BC opposite rays Given
AC is a straight line Definition of opposite rays
∠ABD + ∠CBD = ∠ABC Angle addition postulate
∠ABD + ∠CBD = 180° Definition of linear pair
m∠ABD = 5x + 7 Given
m∠CBD = 9x + 19 Given
5x + 7 + 9x + 19 = 180 Substitution property of equality
14x = 180 - 26 Subtraction property of equality
x = 154/14 Division property of equality
x = 11 Proved
Attached you will see the solution using the trig plane and general solutions.
