What is the section formula in cartesian geometry?<br \/><\/strong><\/h3>\n<p><span style=\"font-weight: 400;\"><strong>Ans: <\/strong>The section formula in coordinate geometry represents the coordinates of the point that divides a line into an m:n ratio. We can find the coordinates of this point using the formula given below.<br \/><span class=\"katex-eq\" data-katex-display=\"false\">(x, y)=\\left(\\frac{m x_{2}+n x_{1}}{m+n},\\frac{m y_{2}+n y_{1}}{m+n}\\right)<\/span><\/span><span style=\"font-weight: 400;\"><\/span><span style=\"font-weight: 400;\"><\/span><\/p>\n<h3><strong>Q2. What is the distance formula in cartesian geometry?<br \/><\/strong><\/h3>\n<p><strong>Ans: <\/strong>The distance formula in cartesian geometry is useful for finding the distance between two points in the coordinate plane. If two points A and B coordinates are <span class=\"katex-eq\" data-katex-display=\"false\">\\left(\\left(x_{1}, y_{1}\\right) \\text { and }\\left(x_{2}, y_{2}\\right)\\right.<\/span> then the distance between these points is given as <span class=\"katex-eq\" data-katex-display=\"false\">d=\\sqrt{\\left(x_{2}-x_{1}\\right)^{2}+\\left(y_{2}-y_{1}\\right)^{2}}<\/span><strong><\/strong><\/p>\n<h3><strong>Q3. What is the slope formula in cartesian geometry?<\/strong><\/h3>\n<p><strong>Ans:\u00a0 <\/strong><span style=\"font-weight: 400;\">The slope of a line is the ratio of vertical change or inclination of the line. The slope of a line inclined at an angle \u03b8 with the positive x-axis is given by m = tan \u03b8.
