Graphing Linear Equations Practice Problems
Grades 7-10 · 5 problems
Practice graphing linear equations by plotting points and using slope-intercept form. This tool provides instant feedback to help you master this essential algebra skill.
Tip: Remember that the slope-intercept form of a linear equation is y = mx + b, where m is the slope and b is the y-intercept. Understanding this form makes graphing much easier!
1
Graph the equation y = x + 2. What is the y-intercept?
2
Graph the equation y = 2x - 1. What is the slope?
3
The line passes through the points (1, 5) and (3, 9). What is the equation of the line in slope-intercept form?
4
What is the x-intercept of the line represented by the equation 3x + 4y = 12?
5
Two lines are perpendicular. One line has the equation y = (-1/3)x + 5. What is the slope of the other line?
Common Mistakes
- Confusing the x and y intercepts.
- Incorrectly calculating the slope (rise over run).
- Forgetting to distribute when converting from point-slope form to slope-intercept form.
