Without the multiplication signs, the linear equation:

a = 4 x c - 2 x d

is written as:

• a = 4c x 2d

• a = 4c - 2d

• a = 4c2d

• 4c - 2d

If y represents a number, the expression for 2 less than 5 times that number is:

• 5 - 2y

• 5y - 2

• 2y - 5

• 2 - 5y

The linear equation for this table is

• b = a + 5

• b = 3a

• b = a + 2

• b = a - 2

The linear equation for this table is

• w = r + 5

• w = 5r

• w = 2r + 5

• w = r - 5

The linear equation for this table is

• w = 8m

• w = 2m + 6

• w = m + 7

• w = 2m + 5

The linear equation for this table is

• k = 5g

• k = 4g + 2

• k = g + 8
