When reading the graph from left to right, the line falls if the slope is negative. The line gets steeper as the absolute value of the slope get larger. (look at the numeral of the slope, not the sign) For example a slope of 2 is steeper than a slope of 1/4. A slope of -3 is much steeper than a slope of 1.
The slope m of a line passing through two points ( x 1, y 1) and ( x 2, y 2) is: m = y 2 − y 1 x 2 − x 1. If the graph of a line rises from left to right, the slope is positive. If the graph of the line falls from left to right the slope is negative.
As you can see, the line goes up 2 points for every 1 points it goes right, meaning that the change in y is 2 when the change in x is 1. Slope = 2. For more information, please view our lesson on graphing lines. Summary. The slope of a line is the change in y divided by the change in x between two points.
course of several days. Lesson one focused on recognizing linear graphs, and lesson two focuses on the introduction of the new terminology rate of change and slope . Lesson three will present the terms x intercept and y intercept. Performance Objectives : 1.
Recall from Lesson 6-6 that two quantities are proportional if they have the same ratio. The side lengths of the similar triangles above have the same simplified ratio, _2 3. Note that the slope of the line is also _2 3. Both the slope and the simplified ratio of the side lengths of the graph above are positive.
Group Lessons: Our group lesson will be taught on the large deck and will consist of 2 students (we can accommodate a 3rd student for free; however the 3 students may be taught in rotation). Our regular rate is HK$1 45 0 (Only HK$ 1233 with the special 15% discount) per group for each 55 minutes session .
