Question

What formula is used to show lines are parallelto one another?​

Answer 1

If you wanna find out if 2 lines are parallel you should compare the slopes. Pick two points XY to find the slope. Then put it into the formula y2 minus y1 divided by x2 minus x1. Then calculate the slope of both lines, if they are the same then the lines are parallel.

Answer 2

Answer:

To figure out if 2 lines are parallel, compare their slopes. You can find the slope of a line by picking 2 points with XY coordinates, then put those coordinates into the formula Y2 minus Y1 divided by X2 minus X1. Calculate the slope of both lines. If they are the same, then the lines are parallel.
