Arrows in the axes indicate the positive directions. AÌCÌ = 3 â 1 = 2. Similarly, you can figure out the positions for the points M = (2, 1.5) The length of 1. We welcome your feedback, comments and questions about this site or page. y = Â½ x + 1 because their slopes are both the same. Slope is the ratio of the of the plane. / Exam Questions - Straight lines. For example: The line y = Â½ x - 1 is Earlier, we featured a blog of Coordinate Geometry practice questions. On the coordinate plane, the slant of a line is called the slope. 0 Plot the following points: A(-3,2), B(-1,4), C(-2,-4), D(0,-2), E(3,0). The height is the y coordinate of the point of intersection of the lines y = x and y = -2x + 3 found by solving the system of equations. positions along the x and y-axes. B. The midpoint between the two points (x1,y1) and (x2,y2) is, For example: The midpoint of the points A(1,4) D. 3.5. Question 2: Who is the father of coordinate geometry?
