The geometrical representation of a linear equation

• Straight line

• Curve

• Parabola

• Either (b) or (c)

The reason that a degree one polynomial equation ax + by + c = 0 is called a linear equation is that

• It has infinitely many solution

• The geometrical representation is a straight line

• It has two variables

• Both a and b

Which equation is written in STANDARD form?

• y = 1/2x + 2

• y - 3 = -5(x + 2)

• -7x + 2y = 9

• 3x + 2 = y

Write an equation in Standard Form.
A store sells t-shirts for $12 each and sweatshirts for $15 each. You plan to spend $120 on t-shirts and sweatshirts.

• 2x + 5y = 120

• 12x + 15y = 120

• 12 + 15y = 2x

• 12x + 15 = 120

If (2, 0) is a solution of the linear equation 2x + 3y = k, then the value of k is.

• 4

• 6

• 5

• 2

The equation x = 7, in two variables, can be written as

• x + 1. y = 7

• X + 0. y = 7

• x + 1. y = 7

• x + 0. Y = 7
