Linear Functions 3

Find the slope between the two given points: (-2,1) and (5,7)

• $\frac{7}{6}$

• 2

• $\frac{6}{7}$
  

• -2

Find slope:

• m= 4

• m=1/4

• m=-4

• m=-1/4

What is the x-intercept? (Find the equation first)

• 1

• 2

• -2

• 0

What point is the y-intercept?

• (2,0)

• (0,2)

• (0,-2)

• (1, 0)

Does this mapping diagram represent a function?

• No, because there are repeating input values
• Yes, because there are no repeating input values

Writing Equations:

Given the following table, write the linear equation.

• y = 9x + 3

• y = 3x + 12

• y = 3x + 9

• y = 1x + 12

Look at the table below. Write an equation to match the pattern between m, minutes and bubbles blown, b.

• b = 12(m)
• b= m +12
• b = m ÷ 12
• none of these

Write the equation. What is the zero?

• -5

• 0

• 6

• 1.2

Transform from standard form to slope intercept form: 2x-3y=10

• y=-2x+10

• 
  

  $y=\frac{2}{3}x-\frac{10}{3}$

• $y=-\frac{2}{3}x+\frac{10}{3}$
  

• $y=\frac{2}{3}x+10$
  

Write the equation.

• f(x) = 3x - 7
• f(x) = 3x - 1
• f(x) = 3x - 4
• f(x) = 2x + 3
