The answer is no! use this only as the slope of the parallel line because they must be equal. instead, take the opposite reciprocal (also known as negative reciprocal) of the given slope. therefore, to get the equation of the perpendicular line, use. graph the line to verify if it is perpendicular to the reference line and has passed through. Find the equation of the line that is: parallel to y = 2x 1; and passes though the point (5,4) the slope of y = 2x 1 is 2. the parallel line needs to have the same slope of 2. we can solve it by using the "point slope" equation of a line: y − y 1 = 2(x − x 1) and then put in the point (5,4): y − 4 = 2(x − 5) that is an answer!. Solution: step 1: find the slope . first, find the slope of the given line. to do this, solve for to change standard form to slope intercept form, . in this form, you can see that the slope is , and thus . step 2: substitute the slope you found and the given point into the point slope form of an equation for a line.
