Answer

Here are the equations of the lines passing through each pair of points: 1. \( y = -5 \) 2. \( y = x + 4 \) 3. \( y = \frac{1}{4}x - 3 \) 4. \( y = -\frac{1}{2}x - \frac{3}{2} \) 5. \( x = -5 \) 6. \( y = -1 \) 7. \( y = \frac{5}{7}x + \frac{10}{7} \) 8. \( y = -\frac{1}{2}x \) 9. \( y = -\frac{3}{2}x - 4 \) 10. \( y = -2x + 1 \) 11. \( y = \frac{1}{4}x + 3 \) 12. \( y = -\frac{5}{6}x + \frac{5}{3} \)

Solution

Sure! Below are the equations of the lines passing through each pair of points you've provided: --- **1)** Through: \( (0, -5) \) and \( (-2, -5) \) - **Type:** Horizontal Line - **Equation:** \[ y = -5 \] --- **3)** Through: \( (0, 4) \) and \( (-3, 1) \) - **Slope Calculation:** \[ m = \frac{1 - 4}{-3 - 0} = \frac{-3}{-3} = 1 \] - **Equation:** \[ y = x + 4 \] --- **5)** Through: \( (-4, -4) \) and \( (0, -3) \) - **Slope Calculation:** \[ m = \frac{-3 - (-4)}{0 - (-4)} = \frac{1}{4} \] - **Equation:** \[ y = \frac{1}{4}x - 3 \] --- **7)** Through: \( (-1, -1) \) and \( (-3, 0) \) - **Slope Calculation:** \[ m = \frac{0 - (-1)}{-3 - (-1)} = \frac{1}{-2} = -\frac{1}{2} \] - **Equation:** \[ y = -\frac{1}{2}x - \frac{3}{2} \] --- **9)** Through: \( (-5, 0) \) and \( (-5, -3) \) - **Type:** Vertical Line - **Equation:** \[ x = -5 \] --- **29)** Through: \( (3, -1) \) and \( (-4, -1) \) - **Type:** Horizontal Line - **Equation:** \[ y = -1 \] --- **30)** Through: \( (5, 5) \) and \( (-2, 0) \) - **Slope Calculation:** \[ m = \frac{0 - 5}{-2 - 5} = \frac{-5}{-7} = \frac{5}{7} \] - **Equation:** \[ y = \frac{5}{7}x + \frac{10}{7} \] --- **32)** Through: \( (-4, 2) \) and \( (-2, 1) \) - **Slope Calculation:** \[ m = \frac{1 - 2}{-2 - (-4)} = \frac{-1}{2} = -\frac{1}{2} \] - **Equation:** \[ y = -\frac{1}{2}x \] --- **34)** Through: \( (0, -4) \) and \( (-2, -1) \) - **Slope Calculation:** \[ m = \frac{-1 - (-4)}{-2 - 0} = \frac{3}{-2} = -\frac{3}{2} \] - **Equation:** \[ y = -\frac{3}{2}x - 4 \] --- **36)** Through: \( (0, 1) \) and \( (-2, 5) \) - **Slope Calculation:** \[ m = \frac{5 - 1}{-2 - 0} = \frac{4}{-2} = -2 \] - **Equation:** \[ y = -2x + 1 \] --- **38)** Through: \( (0, 3) \) and \( (-4, 2) \) - **Slope Calculation:** \[ m = \frac{2 - 3}{-4 - 0} = \frac{-1}{-4} = \frac{1}{4} \] - **Equation:** \[ y = \frac{1}{4}x + 3 \] --- **40)** Through: \( (2, 0) \) and \( (-4, 5) \) - **Slope Calculation:** \[ m = \frac{5 - 0}{-4 - 2} = \frac{5}{-6} = -\frac{5}{6} \] - **Equation:** \[ y = -\frac{5}{6}x + \frac{5}{3} \] --- If you need further assistance or explanations on any of these equations, feel free to ask!

Extra Insights

Did you know that the concept of plotting points on a Cartesian plane dates back to the late 16th century? Mathematicians like René Descartes and Pierre de Fermat pioneered this method to analyze geometry algebraically. They discovered that by using coordinates, you could transform geometrical problems into algebraic equations — a game changer for mathematics that still influences how we visualize and solve problems today! In real-world applications, the use of coordinate systems is everywhere! From plotting locations on a map to tracking the trajectory of a roller coaster, understanding points and lines helps us navigate through our everyday lives. For instance, businesses utilize this information to optimize delivery routes or urban planners use it to design efficient city layouts, making our environments more functional and enjoyable!
