This app solves linear equations step by step and plots the result. All the performed calculations are stored in the history. Just enter m, n or two coordinate points and the equation is solved. The final solution can be shared. [ What you get ] - solving logic for different inputs like: - two points - one point and slope - one point and intersection with axis of ordinates - linear equation and x coordinate - linear equation and y coordinate - the input supports decimals and fractions - plot of the result - history function that keeps your given inputs - full solution shown in all necessary steps - no ads! [ How to use ] - there are 6 fields where you can insert any value with a modified keyboard - m for the slope - n for the intersection with the axis of ordinates - x1, y1 and x2, y2 as coordinates for the points - if you enter 3 or 4 values (depending on the calculation you need) and hit the calculate button, the app switches to the solution page - when you hit the calculate button without giving enough values, the app marks it as yellow - when you hit the calculate button with giving invalid values, the app marks it as red - you can tap and/or swipe to get to the solution or history page - the history entries can be deleted or put in order manually - if you click on one history entry, the app will load it to the inputs - you can delete all history entries by using a button
