HOW TO CALCULATE SLOPE OF A LINE

THIS PRESENTATION IS USEFUL TO GRADE 10 AND GRADE 11 MATH STUDENTS LEARNING COORDINATE GEOMETRY.
DIFFERENT FORMULAE FOR SLOPE ARE ILLUSTRATED WITH THE RELEVANT FORMULAE.
THIS IS A QUICK AND EASY WAY TO LEARN SLOPE.
THIS IS ALSO USEFUL FOR THE GRE QUANT, SAT AND ACT EXAMS.

1. GRADE 11 MATH GRADE 10 MATH SUMAN MATHEWS SLOPE AND EQUATION OF A LINE

2. PREVIEW: THIS VIDEO ILLUSTRATES HOW TO CALCULATE THE SLOPE AND PROBLEMS OF THE FORM y = mx +c . PROBLEMS ARE EXPLAINED IN DETAIL WITH THE RELEVANT FORMULA IN EACH CASE. SO WATCH THIS ENTIRE VIDEO WITH ME!

3. Slope of a line I’d defined as tangent of the angle made by the line with the positive direction of the x axis. It is denoted by m

4. Slope of the x axis = 0 Slope of the y axis is What is the slope of a line which makes an angle 60 degrees with the positive direction of they y axis measured anticlockwise 60  

5. Question 2 What is the slope of the line passing through (2, 3) and(5,-7) Question 3 Find x so that the line through (x,9) and (2,7) is parallel to the line through (2,-2) and (6,4)

6. 2 parallel lines have the same slope If 2 lines are perpendicular, product of the slopes = -1 Question 3 If A(2,-3),B (3,5) are 2 vertices of a rectangle ABCD,find the slope of BC. , CD, DA

7. Slope of AB = Slope of BC = Slope of CD = 8 Slope of DA =

8. Equation of x axis y= 0 Equation of y axis x = 0 Any line parallel to the x axis is y = c Any line parallel to the y axis is x = c Slope intercept form of a line y =m x +c m slope c is the y intercept Find the equation of a straight line parallel to the x axis and having intercept -2 on the y axis y =-2

9. Find the equation of a vertical line passing through (-7,3) x = -7 Find the equation of a line having slope -2/7 , y intercept -3

10. Find the equation of the line whose inclination is y intercept =-5

11. Equation of the line is y = - x - 5 (y = my +c ) For more videos ; subscribe to my channel mathmadeeasy
