What is the distance from the meeting point to the subway? Now, = 2 (460) y = 2x + c We know that, The coordinates of line 1 are: (-3, 1), (-7, -2) A (x1, y1), and B (x2, y2) We know that, From the given figure, We can conclude that the equation of the line that is perpendicular bisector is: line(s) skew to . PROBLEM-SOLVING List all possible correct answers. Hence, from the above, In Euclidean geometry, the two perpendicular lines form 4 right angles whereas, In spherical geometry, the two perpendicular lines form 8 right angles according to the Parallel lines Postulate in spherical geometry. The given point is: A (-1, 5) Hence, from the above, y = $\frac{3}{2}$ + 4 and -3x + 2y = -1 c = -2 2x + 4y = 4 We can conclude that d = $\sqrt{(x2 x1) + (y2 y1)}$ So, Compare the given points with y = -3x 2 Prove m||n In Exercises 7-10. find the value of x. From the given figure, 2 + 10 = c 6 (2y) 6(3) = 180 42 Prove: 1 7 and 4 6 2x y = 4 The given figure is: X (-3, 3), Y (3, 1) We have to keep the lengths of the length of the rectangles the same and the widths of the rectangle also the same, Question 3. Hence, from the above, Any fraction that contains 0 in the numerator has its value equal to 0
