Solving Linear equations

Which of the following is a Linear equation?

• Y = 2x + 5

I think of a number. I multiply it by 10 and add 5 more to it. If my answer is 55. What number did I start with?

• 15

• 7

• 5

• 10

Substitute x = 5 and y = 2 into Y= mx + 8 to find a value of m.

m = ......................

Find the equation for this graph.

• Y = 3x + 4

• Y = 5x + 2

• Y = 6x + 2

• Y = 2x +2

Rearrange the following equation so that Y is the subject of the equation.

-3x + y = 6

New equation: ..............................................................................

Fill in the blanks with use of 3x + Y = 6.

• -1 and 8

• 0 and 9

• 0 and 8

• 9 and -2
