Standard Form of Linear

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

Name the x- and y-intercepts for the equation:
2x + y = 6

• (0, 3) and (6, 0)

• (0, -3) and (-6, 0)

• (3, 0) and (0, 6)

• (-3, 0) and (0, -6)

^{What is the x- intercept of the line?}

• (1, 0)

• (2, 0)

• ( -1, 0)

• (-2, 0)

What are the x- and y-intercepts of the linear function given by the equation x + y = -2

• (-2, -2)

• (-2, 0) and (0, -2)

• (0, 0)

• (2, 0) and (0, 2)

Find the x and y intercepts
4x - 5y = 40

• x intercept is 10 
  y intercept is 8

• x intercept is 10
  y intercept is 20

• x intercept is 8
  y intercept is 10

• x intercept is 10
  y intercept is -8

Which graph represents 2x + 4y = 12?

• 
• 
• 
• 

What is the standard form of a linear equation?

• y = mx + b

• Ax + By = C

• Ay + Bx + C = 0

Which equation is written in STANDARD form?

• y = 1/2x + 2

• y - 3 = -5(x + 2)

• 7x + 2y = 9

• 3x + 2 = y

For an equation written in standard form Ax + By = C, which of these are TRUE?

• y intercept is when x = 0 so plug 0 in for x and solve for y to get the coordinates of the  y intercept  (0,y)

• x intercept is when y = 0 so plug 0 in for y and solve for x to get the coordinates of the  y intercept  (x,0)

Find the slope and y-intercept:

6x + -2y = 18

• slope = -6, y-intercept = -2

• slope = -3, y-intercept = 9

• slope = 3, y -intercept = -9

• slope = 6, y-intercept = 3
