What is the y-intercept of the line y = 4x + 2?
Look for the constant term.
Find the x-intercept of y = -3x + 9.
Set y to 0 and solve for x.
What does the y-intercept represent in a linear equation?
Think about where the line crosses the y-axis.
True or False: The x-intercept is where the line crosses the y-axis.
Remember the definitions of intercepts.
A line crosses the y-axis at 5 and has a slope of -2. Write the equation of the line and find the x-intercept.
Use the slope-intercept form to create the equation.
If a line crosses at (6,0) and (0,-4), find the slope of the line and write its equation.
Remember the formula for slope. Then use the y-intercept.
