1/2
• Question 4
60 seconds
Q. What is the equation for the line that passes through the points (4,2) and (0,6)?
y = x + 6
y = -2x + 2
y = -x - 6
y = -x + 6
• Question 5

b
• Question 6
60 seconds
Q. Write a linear function f with the values f(0) = 6 and f(4) = -6.
y = -3x + 6
y = -6
y = 3x - 6
y = 3x + 6
• Question 7
30 seconds
Q. Write an equation of the line that passes through (3,1) and is parallel to the line y = 3x + 1.
y = -3x + 1
y = 3x - 8
y = -1/3x -8
y = 3x + 4
• Question 8
60 seconds
Q. What is the equation for the line with a slope of 7 and passes through (0,1)?
y = -7x + 1
y = 7x + 1
y = -1/7x - 1
y = -1/7x + 1
