Line Grapher
Enter m and b (fractions welcome) to graph y = mx + b instantly — with intercepts, a value table, and the rise/run staircase drawn in.
1 Line Grapher: y = mx + b
Type the slope and y-intercept as integers, decimals, or fractions like 2/3. The tool draws the line, marks both intercepts, and builds a table.
Input
Key features
Press Graph the line.
Teal dot: y-intercept · gold dot: x-intercept · dashed: rise/run staircase.
Table of values
The table appears after graphing.
2 Reading the graph
The line always crosses the y-axis at (0, b). From there, the slope m = rise/run tells you the staircase to the next point.
