How Do You Find The Equation Of A Line When Given A Point And The Slope?
One of the main tasks in Algebra is to examine lines. There are different forms for the equation of a line and which one to use depends on what information you have about a specific line. In this article, we will look at what to do when given a point on the line and the slope of the line. Determine which form for the equation of a line you should use. This is an easy one. When you are given a point and the slope, use “Point-Slope” form. This is y-y1 = m(x-x1). See pic also. Plug values into the generic point-slope equation. So, x1 is the x-coordinate (first one in the ordered pair) from your point; y1 is the y-coordinate (second one in the ordered pair) from your point; m is the slope. See pic for example. Simplify the parentheses. Use the Distributive Property to eliminate the parentheses on the right hand side. The parentheses on the left don’t really mean anything, so you can simply remove them. See pic. Simplify to get y by itself on the left side of the equation. All that’s left t
