## What do our people say?

They have all evaluates , graph ,parallel , perpendicular all things in math they have from grade 1 to 12, its embarassing to approach tutors for simple things, this app makes the simple things easier, leaves the harder questions for the tutors.

Must have for any math student, huge help, its can help me alot thanks to this app i can easily answer math problem, online videos didn't work but this did, this app is Soooo awesome and superb and beautiful. I am not at all a math person but the breakdown of steps really increases comprehension.

I tried the exact same problem using Photomath and Microsoft Math and they both were not able to determine my handwriting. It is very explanatory and efficient, hands down, best app I have on my phone. This is the best app for math homework I know I've been struggling with algebra being that I'm a 7th frisson school no help due to the coronavirus is the great app Trust.

## Parallel and Perpendicular Lines

Slope of parallel lines. In coordinate geometry, parallel lines have the same slope. The converse is also true; if two lines have the same slope, the two lines are parallel unless they overlap. The blue line below is the graph of the

## Parallel lines

parallel\:2x-3y=9,\:(4,-1) parallel\:y=4x-12,\:(5,6) parallel\:x-y=4,\:(-3,2) parallel\:y=\frac{1}{4}x-3,\:(4,0) parallel\:y=3x-2,\:(-1,3) parallel\:2x-y=8,\:(3,4) ## Parallel lines from equation (example 3)

These lines are parallel, because a pair of Corresponding Angles are equal. These lines are not parallel, because a pair of Consecutive Interior Angles do not add up to 180° (81° + 101° =182°) These lines are parallel, because a pair of Alternate
