From the following equations of straight line determine which pairs are parallel to each other.
a. y = 3x + 7
y=3x + 10
b. 4y =8x – 9
10y= 2x + 3
c. 3y = 5 -4x
5y= 9- 20x
d. 7y = 21x + 10
Y =3x – 6

Write the equation in the form y = mx + C and compare the value of m in equation, m is the gradient of the line.
a. The two are parallel to each other since they have the same gradient of 3.
b. They are not parallel to one another since the first line has a gradient of 2 and the second a
gradient of 1/5.
c. Not parallel the first has a gradient of -4/3 the second line a gradient of -4
d. They are parallel since they have a gradient of 3
