Functions (linear)

Write a linear equation in the form of y=mx+b

• y = -4x +6

• y = 6x - 4

• y = 4x - 6

• y = 3x - 2

In a linear function what is the output?

• y=mx+b

• x

• y

• the b function

The table represents some points on the graph of a linear function. Write the equation of the line in slope-intercept form.

What is the linear equation for this table? (write your answer in y=mx+b form)

If a linear equation has solutions (–2, 2), (0, 0) and (2, – 2), then it is of the form

• (A) y – x = 0

• (B) x + y = 0

• (C) –2x + y = 0

• (D) –x + 2y = 0

What is the linear parent function?

• y = x

• y = mx + b

• Ax + By = C

Which equation represents the table?

• y = 10x

• y = 0.1x

• y = 3x

• y = 30x

The table shown is:

• Proportional because it goes through the origin.
• Linear, because there is a pattern.
• A function, because all of the x values are different.
• All of the above.

• 1

• -2

• 11

• 18

What equation can be used to represent the relationship between the input (x) and output (y)?

• y = x + 4

• y = 3x

• x = y + 4

• x = 3y
