When youre working with equations of lines theres lots of different forms that you might write an equation to describe the same line. None of the slopes are equal or opposite reciprocals, so none of the graphs of the equations are parallel or perpendicular Use the point-slope form formula to find the equation for the parallel line. One answer suggested using parametric line equations to find the intersection between two infinite lines and then resolving if the intersection point fell on the given line segment.In my implementation (using glsl) I am seeing unexpected results as the slope of the line approaches full verticality. This concept is reflected in something called the "slope" of the line. Lets take a look at the straight line.To find the slope, we will need two points from the line. Ill pick two x-values, plug them into the line equation, and solve for each corresponding y-value. Worksheets for slope and graphing linear equations.
