Graphing Linear Equations

What is the slope-intercept form of a linear equation?

• y = mx + b

• y = ax + b

• y = mx - b

• y = mx^2 + b

How do you find the x-intercept of a linear equation?

• Set y equal to zero and solve for x.

• Set y equal to one and solve for x.

• Set x equal to one and solve for y.

• Set x equal to zero and solve for y.

How do you find the y-intercept of a linear equation?

• The y-intercept is the point where the line crosses the x-axis.

• The y-intercept is the slope of the line.

• The y-intercept is always equal to zero.

• The y-intercept is the point where the line crosses the y-axis.

What is the slope of a line parallel to the y-axis?

• undefined

• negative

• positive

• zero

How do you graph a linear equation using the slope-intercept form?

• Identify the slope and x-intercept, plot the x-intercept, use the slope to find additional points, and connect the points to graph the linear equation.

• Identify the slope and y-intercept, plot the x-intercept, use the slope to find additional points, and connect the points to graph the linear equation.

• Identify the x-intercept and y-intercept, plot the x-intercept, use the slope to find additional points, and connect the points to graph the linear equation.
