is a straight line
is a relationship between two variables
can be described using slope and y-intercept
all of the above
none of the above
- 2. Multiple Choice
The rate of change of a linear relation is:
the slope
the y-intercept
the equation of a line
none of the above
all of the above
- 3. Multiple Choice
The two key characteristics of a linear relation are:
slope and initial value
slope and y-intercept
rate of change and initial value
rate of change and y-intercept
all of the above
- 4. Multiple Choice
This linear relation has
a y-intercept of +2
a positive slope
a negative slope
no y-intercept
- 5. Multiple Choice
This linear relation has
a y-intercept of +2
no slope
a negative slope
no y-intercept
- 6. Multiple Choice
This linear relation has
a y-intercept of +2
no slope
a negative slope
no y-intercept
- 7. Multiple Choice
The "Positive Slope" property states that:
the line goes down
two lines have the same slope
the line goes up
the line is steeper
- 8. Multiple Choice
The "Negative Slope" property states that:
the line goes down
two lines have the same slope
the line goes up
the line is steeper
- 9. Multiple Choice
The "Parallel Lines" property states that:
the line goes down
two lines have the same slope
the line goes up
the line is steeper
- 10. Multiple Choice
The "Higher Slopes" property states that:
the line goes down
two lines have the same slope
the line goes up
the line is steeper
- 11. Multiple Choice
Slope is calculated by
finding the point where the line crosses the y-axis
finding the point where the line crosses the x-axis
- 12. Multiple Choice
The y-intercept is determined by
finding the point where the line crosses the y-axis
finding the point where the line crosses the x-axis
- 13. Multiple Choice
The equation of a line is
y = x + mb
x = my + b
y = mx + b
y = bx + m
- 14. Multiple Choice
If m = 4 and b = -1, the equation of the line is
y = -1x + 4
y = 4x - 1
y = -4x + 1
y = 1x - 4
- 15. Multiple Choice
If the slope of a line is 5 and its y-intercept is 0, the equation of the line is
y = 5
y = 5x
y = -5
y = -5x
- 16. Multiple Choice
If the initial value of a relation is 200 and the rate of change is 50, the equation of the line is
y = 200x + 50
y = 50 + 200x
y = 200
y = 50x + 200
