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
