Algebra Standard Form Linear

Why is the following equation not in standard form?
-3x + 2y = -9

• -3 in front of x

• -9 is on the wrong side

• 2y is positive

• x and y are on the wrong side

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

Alainah, Autumn, and Faith are planning a hiking trip. They found a map with a clue that says '-4x + 5y = 20'. They need to convert this linear equation into slope-intercept form to find the correct trail. Can you help them out? (Be careful with the signs!)

• y = (4/5)x + 4

• y = (4/5)x - 20

• y = (-4/5)x - 20

• y = (5/4)x + 20

Makinzie, Kara, and Ethan are on a mission to find a hidden artifact. They stumbled upon a clue which is an equation written in STANDARD form. Can you help them decipher the correct clue?

• y = 1/2x + 2

• y - 3 = -5(x + 2)

• -7x + 2y = 9

• 3x + 2 = y

Ella, Klara, and Robert are on a mission to save their friend Autumn who has been captured by a villain. The villain left a clue that says 'Find the equation written in STANDARD form'. Can you help them solve the clue and save Autumn?

• y = 1/2x + 2

• y - 3 = -5(x + 2)

• 7x + 2y = 9

• 3x + 2 = y

Jireh, Xavier, and Elliot are working on a project for their math class. They are tasked with creating a model of a city using linear equations. They come across a problem that asks: 'How would you write the linear equation 2x - 3y = 6 in slope-intercept form? Remember, you must perform all inverse operations to ALL terms.'

• y = (3/2)x - 6

• y = (2/3)x + 3

• y = (2/3)x - 2

• y = (3/2)x + 6
