How to fill out 1 linear functions and

How to fill out 1 linear functions and:

1. Start by understanding the concept of linear functions: A linear function is a mathematical function that represents a straight line on a graph. It has the form f(x) = mx + b, where m is the slope of the line and b is the y-intercept.
2. Identify the given information: To fill out a linear function, you need to know at least two points on the line or the slope and one point. If you have the equation of the line, you can easily determine the slope and y-intercept.
3. Calculate the slope: If you have two points on the line, you can find the slope using the formula: m = (y2 - y1) / (x2 - x1), where (x1, y1) and (x2, y2) are the coordinates of the two points.
4. Determine the y-intercept: If you already have the equation in the form f(x) = mx + b, the y-intercept is given by the value of b. If you don't have the equation, you can use one of the given points and the slope to solve for b. Substitute the coordinates of the point and the slope into the equation and solve for b.
5. Write the linear function: Once you have the slope and the y-intercept, you can write the equation of the linear function. Substitute the slope for m and the y-intercept for b in the form f(x) = mx + b.
