1. Find the gradient of each
line.
c) 1; d) –2.
2. The equation of any straight line can be
written in the form
y = mx
+ c
where m
is the gradient and c is where the line crosses the y-axis.
Which lines below
have the same gradient?
y = 3x
+ 1, y = 3x – 2, y = 2x + 3, y = 3 + 4x, y = 7 + 3x.
а) y =
3 + 4x, y = 2x + 3, y = 7 + 3x;
b) y =
3 + 4x, y = 3x – 2, y = 2x
+ 3;
c) y =
2x + 3, y = 3x – 2, y = 3 + 4x;
d) y =
3x + 1, y = 3x – 2, y = 7 + 3x.
