Answer: x = 12 Question 7. a. Answer: y = 3x + 2, (b) perpendicular to the line y = 3x 5. Answer: 2 ________ by the Corresponding Angles Theorem (Thm. The given figure is: We have seen that the graph of a line is completely determined by two points or one point and its slope. We can observe that y = \(\frac{2}{3}\)x + 1, c. The slope of the line that is aprallle to the given line equation is: If the corresponding angles formed are congruent, then two lines l and m are cut by a transversal. So, Answer: Now, The completed table is: Question 6. = \(\sqrt{(9 3) + (9 3)}\) Determine the slope of a line perpendicular to \(3x7y=21\). An equation of the line representing the nature trail is y = \(\frac{1}{3}\)x 4.
