Homework 3 – BH2.6

Calculators must not be used for the following questions. Show all necessary working.

Calculate the gradient of the line joining each pair of points

1. a) A ( 2 , -1 )

B ( 4 , 7 ) b) X ( -1 , 1 )

Y ( 5 , 13 ) c) R ( -2 , -5 )

S ( 2 , -7 )

2. Write down the gradient and y – intercept of the following lines a) y = 3x – 2 b) y = x + 4 c) y = 4x d) y = - 2x – 1

3. Rearrange these equations in the form y = mx + c and then write down the gradient and y – intercept : a) y – 2 x = 3 b) y – x + 3 = 0

4. Write down the equation of the line with :

a) gradient 2 and y-intercept -1

b)gradient -3 and passing through the origin

5. In which pairs are the lines parallel – give reason for your answer a) y = 2x – 5 y = 2x + 1 b) y = 3x + 6 y = 6x + 6 c) y – x = 3 y – x = 0

Homework 4 – BH2.9

1 Alloys are made by mixing metals. Two different alloys are made using iron and lead.

To make the first alloy 3 cubic centimetres of iron and 4 cubic centimetres of lead are used . This alloy weighs 65 grams. a) Let x be the weight of 1 cubic centimetre of iron and y be the weight of 1 cubic centimetre of lead – write an equation using x and y which satisfies this condition.

To make the second alloy 5 cubic centimetres of iron and 7 cubic centimetres of

lead are used. This alloy weighs 112 grams. b) Write an equation using x and y which satisfies this condition. c) Find the weight of 1 cubic centimetre of iron and 1 cubic centimetre of lead.
