In a direct variation, y = 39 when x = 3. 
Find the value of y when x = 2.

• 26
• 3
• 58.5
• 2

What is the Domain?

• -3 ≤ x < 5
• -3 ≤ y < 5
• -8 ≤ x < 5
• -8 ≤ y < 5

Answer explanation

Put the function into desmos

Match the following

• y = -¹/₂ x + 4

• 
• y = -2x + 1

• 
• y = –x + 4

• 

The equation shown in the graph is:

y = ​ (a)   x + ​ (b)  

• 2/3
• 1
• 3/2
• 2
• 3
• 1/3
• 1/2

What is the slope of the line through the points (4, 0) and (-1, 10)?

• -10/3

• 3/10

• 2

• -2

• slope-intercept form

• standard form

• point-slope form

• linear form

Write the equation of the line in point-slope form that goes through the point (10,5) and has a slope of -3

• y - 5 = -3(x - 10)

• y = -3x + 35

• y + 5 = -3(x + 10)

• y = -3x - 35

For the equation
y + 1 = -3 (x - 5),
the line contains the point (5, -1) and has a slope of?

• -1
• 1
• -3
• 5
