Slope-Intercept Form, Point-Slope Form and Standard Form

Which of these represents standard form of a linear equation?

• y - y₁ = m(x-x₁)

• Ax + By = C

• y = mx + b

Which equation is written in STANDARD form?

• y = 1/2x + 2

• y = 2x + 1

• 7x + 2y = 9

• y = x

Which is the correct standard form for: y = -3x + 4

• y - 3x = 4

• -3x + y = 4

• 3x + y = 4

• y + 3x = 4

Write the standard form of the equation for the line.

• 4x + 7y = 4

• 7x + 4y = 4

• 4x - 7y = -35

• 7x + 4y = 35

turn the following equation, y = 4x + 2, into standard form.

• 2y = 4x + 2

• 4x + y = 2

• -4x + y = 2

^{Write in standard form.
y = - 1/2x + 2}

• x - 2y = 4

• x + 2y = 4

• 1/2x - y = 2

• -x + 2y = 2

Write the equation in standard form: 20x - 28 = 4y

• 5x - y = 7

• 10x - 14 = 2y

• 10x - 2y = 14

• 5x - 7 = y

On his notes on linear equation in two variables, Ram found an equation 2𝑥 + 3𝑦 - 10 = 0. If you were Ram, how would you describe the equation according to its form?

• It has constant

• It has variables

• It is in standard form

• It is in slope-intercept form

Why is the following equation not in standard form?
4x + 1/4y = -10

• -10

• 1/4 y

• x and y in the wrong place

• -10 on the wrong side

Write an equation in Standard Form. Jenny went to the sale at Kohl's last weekend.   T-shirts were on sale for $15 each and hoodies were on sale for $20 each.  If she spent $150 total, write an equation to represent this situation.  Let x represent the number of t-shirts and y represent the number of hoodies that she purchased.

• 20x + 15 = y 

• 20x - 15y = 150

• 15x + 20y = 150 

• 150 - 20x = 15y
