Addition and subtraction - ways to make a number - up to 20
What you'll learn
- Calculate the slope of a line given two points on the line with at least 80% accuracy.
- Explain in writing how to use the slope formula (m = (y2 - y1) / (x2 - x1)) to find the slope between two points, including identifying which values represent the change in vertical distance (rise) and the change in horizontal distance (run).
- Identify whether the slope of a line is positive, negative, zero, or undefined when given two points and be correct in at least 4 out of 5 examples.
- Solve real-world problems involving slope, such as determining the steepness of a ramp or the rate of change of a linear function, and show work for how the slope was calculated.
