ðŸ‘‰ Learn how to prove parallel lines and relationship between parallel lines and transversals. You also learn how to find the missing value to show you that

We have two possibilities here: If the alternate interior angles are equal, the lines are parallel. We can match top inside left with bottom inside right or top inside right with bottom inside

y = m1x + b1. y = m2x + b2. then the slopes are m 1, m 2 and the y-intercepts are b 1, b 2. To show that two lines are parallel, we need: m1 = m2 ( the two lines have the same slope) b1 != b2 (the

Answer (1 of 9): If they are parallel, they will have the same gradient. I.e: y=5x+12 and y=5x+31324.142314 are parallel as their gradients are both 5.
