QUESTIONS

Observe the behaviour of the sailing boat.

1. What have you notice to the behaviour of the sailing boat? 2. Tell something about the movement of the sailing boat.

3. Is the sailing boat travels smoothly? Why?

4. If you are the sailor of the said boat, how would you feel sailing in a) Fair weather?

b) Stormy weather?

5. Does the sail of the boat maintain a certain degree of stiffness? 6. Does the stiffness of the sail affect the velocity of the boat?

.This lesson will help you to obtain the slope and the y – intercept of a line from the general equation. You will reduce the general forms to the slope – intercept form by solving for y and the resulting coefficient of x is the slope and b, the y – intercept.

.To reduce the equation in standard form or general form, transform it to the slope – intercept form which is then called non – standard form and find the slope and y – intercept. 1. 6x – 8y + 16 =0

2. 4x + 2y = – 8

. What is the resulting slope – intercept form of the given equations? .What is its slope or m?

. What is its y – intercept or b?

.Transform the equations into slope – intercept form, and find the m and b of each equation. 3x + 4y = 10

2x + y = 5

Solve:

Given:

Point A( -1, -1 ), point B( 0, -2 ) and point C( 2,1 ).

1. Show that the three points are vertices of a Triangle.

2. Find the slope of each line.

3. What kind of triangle is formed?

4. Prove your answer.

.Functions serves as a meaningful way of applying mathematics to many real world situations and problems. They are efficient models of the relationships of two quantities that change with one another according to certain conditions. The ratio of the change in the dependent variable to the independent variable is called the slope of the line. .The general form r standard form of a linear function can be transform into a non-standard form, the Slope – Intercept Form or f(x) = mx + b. .Coronel, Antonio C. et. al.
