Gradient of the line joining the two points

Reference no: EM13938845

i) Give the values of m and c in the following equations

a) y = 3x + 3 b) y = 6x + 2 c) y = 3x - 5

d) y = 1/2x - 8 e) 3y = 9x - 18 f) 1/2y = 3x + 1

g) 1/3y = 6 - 2x h) 3y + x = 12 i) 2y = 8 - x

ii) Identify which lines are parallel (Hint :- Parallel line have the same gradient and perpendicular lines when their gradients are multiplied you get -1)

2) Find the gradient of the line joining the two points

a) (10, 3) and (2, 1)

b) (3, 5) and ( 5, -3)

c) (2, 8) and (6, 0)

3) Plot the graph for ( Not for submission, simply give the points to be plotted in a table form)

a) y = 2x - 2 -3 ≤ x ≤ 5

b) y = x2 - x - 6 -3 ≤ x ≤ 5

4) Find the point of intersection between

i) y = x2 + 4x - 10 and y = 3x - 4

ii) y = x2 - 3x + 6 and y = 3x - 2

5) Using the graph in 3 solve the quadratic equation x2 - 3x - 4 = 0
