Graphing Linear Functions SY24

The y-intercept is where a linear function ______________.

• y = 0

• crosses the x-axis 
• crosses the y-axis 
• x = 0

• ends

Which equation is written in STANDARD form?

(Remember that the standard form is of a linear equation is Ax + By = C)

• y = 1/2x + 2

• y - 3 = -5(x + 2)

• 7x - 2y = -9

• -7x + 2y = 9

Give the x-intercept of 3x + 8y = 24

(Remember that the x-intercept is where y = 0.)

• (8, 0)
• (0, 8)
• (3, 0)
• (0, 3)

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

^{(Remember the x-intercept is where the line crosses the x-axis.)}

• (1, 0)
• (2, 0)
• ( -1, 0)
• (-2, 0)

What are the x- and y- intercepts on this graph?

• (0,5)

  (0,5)

• (5,0)

  (5,0)

• (5,0)

  (0,5)

• (0,0)

  (5,0)

Put the following equation into Standard Form y = -2x + 6.

(Remember that the standard form is of a linear equation is Ax + By = C)

• 2x + y = 6

• 6 + y = -2x

• y = 6 - 2x

• 3y + 2x = 12

• 6x - y = -7

• -6x + y = 7

• 6x = -y + 7

• y - 6x = 7

What is the y-intercept?

(Hint: the y-intercept is where x = 0.)

• (0, 7)

• (0, 0)
• (0, 1)

• (0, 2)

Which ordered pair could represent a y-intercept on a graph?

(Hint: the y-intercept is where x = 0.)

• (6, 0)
• (0, 4)
• (-1, 3)
• (2, 0)

Give the y-intercept of the following graph.

(Remember that the y-intercept is where the line crosses the y-axis)

• (2, 0)

• (-2, 0)

• (0, -2)

• There is no y-intercept.
