Find the slope of the given line by solving for y.y mx bThe slope of parallel lines are equal. What is a perpendicular line? Analyze Slope Step-by-step Lesson - Based on the slope, are the lines parallel or perpendicular?(Click Here to Upgrade). Homework Sheets. When you have the same slope as another line, that says a lot about you. Parallel lines same slope pependicular slopes are "negative reciprocals" line looks like this: y mx c where "m" is a number that represents the slope. parallel same value for m perpendicular if one line is m, then the other is -1/m. Warning: If a question asks you whether two given lines are "parallel, perpendicular, or neither", you must answer that question by finding their slopes, not by drawing a picture! Pictures can only give you a rough idea of what is going on. Multiple Choice Identify the choice that best completes the statement or answers the question. 1. Find the slope of AB for A(3,5), B(2,7) . Use slopes to determine whether the lines AB and CDare parallel, perpendicular, or neither.
