Linear functions are pretty simple to understand, and here are some important points about them:
Form: You can write them like this: ( y = mx + c ). In this equation, ( m ) is the slope, and ( c ) is where the line crosses the y-axis.
Graph: When you look at their graph, you'll see straight lines.
Slope: The slope (or ( m )) tells us how steep the line is. If the slope is positive, the line goes up as you move from left to right. If it's negative, the line goes down.
Intercepts: The line crosses the y-axis at ( c ). Sometimes, it can also cross the x-axis, which happens when ( y = 0 ).
In short, linear functions are really important in algebra!
