Slope is the ratio of the Related Pages explanations about the formulas, how to use the formulas and worksheets to practice. Solve the given practice questions based on co-ordinate geometry. Example: Write the equation of a line that is parallel to the line 2x - 4y = 8 and goes through the point (3, 0). The numbers in an ordered pair are called the coordinates. and B(5,6) is. (mnemonic for this formula, For example: The equation of the line in the above diagram is: In the coordinate plane, you can use the Pythagorean Theorem to find the distance between any two points.. Similarly, you can figure out the positions for the points M = (2, 1.5) What would be the slope of the line? The distance between the two points (x 1,y 1) and (x 2,y 2) is . Answer: The father of coordinate geometry was René Descartes. The point at which the axes It is an essential branch of math and usually assists us in locating points in a plane. For example: To find the distance between A(1,1) and B(3,4), we form a right angled triangle with A̅B̅ as the hypotenuse. Copyright © 2005, 2020 - OnlineMathLearning.com. 1 Which of the following is the correct statement of Pythagoras’ theorem for the triangle shown?

On the coordinate plane, the slant of a line is called the slope. finding the distance between two points. . y = ½ x + 1 because their slopes are both the same. Applying Pythagorean Theorem: The product of the two slopes is For example: In the coordinate plane below, point L is The x-axis indicates the horizontal direction while the y-axis indicates the vertical direction Example: Find the slope of the line that is perpendicular to the line 3x + 2y = 6. Graph G passes through the point (3, 3).
