Linear Standard Equation

Write the equation of the line in standard form

• 2x + y = -3

• 3x + y = -2

• -2x + y = -3

• -2x + y = 3

Find the slope and y-intercept of the following:

3x - y = 9

• Slope = 3, y-intercept = -9

• Slope = 9, y-intercept = 3

• Slope = 3, y-intercept = 9

• Slope = -1, y-intercept = 3

Write the standard form equation that passes through (0, -1) and (-6, -9)

• -4x +3y = -4

• -4x +3y = -3

• -4x +3y = 5

• -4x +3y = 10

Write an linear equation to model the following:
You want to buy desserts, ice-cream is $2.50 per scoop and puppychow is $4 per bag and you want to spend $20. 

• y=2.50x+4

• 2.50x+4y=20

• y=4x+2.5

Sam ordered 4 tacos and 5 enchiladas for lunch at the restaurant. His bill came to $10.80. Which equation matches the given situation?

• 4x + 3y = 8.10

• 4x + 5y = 10.80

• 4x - 5y = 10.80

• 4x + 10.80y = 5

Easy Car Rental charges $8.50 an hour plus a rental fee of $25.50. Which equation represents the total charges for x hours?

• y = 8.5 + 25.5

• y = 25.5 + 8.5x

• y = 8.5 + 25.5x

Write the slope intercept form of the equation x - 3y = 6

• y = -x - 2

• y = x + 2

• y = 1/3x - 2

• y = -1/3x + 2

What is the equation of this line?

• 0

• undefined 

• y = -2

• x = -2
