Use the graph (or the test question) to find the x and y coordinates of two points on the graph. They can be any two points that the line crosses through. For an example, assume that the line in this method goes through (2,4) and (6,6).Depending on the information provided, you can choose the form to determine the equation of a line. Step 1: Notice the data provided in the given problem. Step 2: Choose the appropriate form of the equation. If the coordinates of one point on the line ( x 1, y 1) and the slope m are given, use the point-slope form.Slope formula: m = (y2-y1)/ (x2-x1) Point-Slope: y-y1 = m (x-x1) Basically, the slope formula has been multiplied on both sides by (x2-x1). Then the x2 and y2 have been changed to just x and y. This form of a linear equation is useful when you are creating the equation of a line. All you need is the slope of the line (m) and one point from the ...3 --> y = mx + b =. y = 3x + b. 3. Plug the points of the midpoint into the line. You already know that the midpoint of the points (2, 5) and (8, 3) is (5, 4). Since the perpendicular bisector runs through the midpoint of the two lines, you can plug the coordinates of the midpoint into the equation of the line. Y-intercept calculator. Instructions: Use this calculator to find the y-intercept of a line, showing you the process step-by-step. The first thing you need to do is to indicate the line you want to the y-intercept of. You have several options to state the line. You can provide: (1) any linear equation (ex: x + 3y = 2 + \frac {2} {3}x x +3y = 2 ... .
