Evaluate a linear function
Evaluate a linear function
What you'll learn
- Given a linear function in slope-intercept form (y = mx + b) and a specific x-value, students will be able to calculate the corresponding y-value with 80% accuracy.
- Students will be able to explain the meaning of f(x) notation and how it relates to evaluating a linear function, using at least two complete sentences in their own words.
- Students will be able to identify the slope and y-intercept from a linear function written in slope-intercept form (y = mx + b) and use these values to evaluate the function for a given x-value with 75% accuracy.
- Students will be able to solve for the value of 'x' when given 'y' and a linear function expressed as y = mx + b with 80% accuracy.
