Graphing Lines: Slope-Intercept and Standard Forms

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

• y = mx + b

• y = mx + c

• y = mx - b

• y = ax + b

What is the standard form of a linear equation?

• Ax + By = E

• Ax + By = C

• Ax + By = D

• Ax + By = F

How do you graph a line in slope-intercept form?

• Identify the y-intercept and use the slope to find additional points on the line.

• Use the x-intercept and the slope to find additional points on the line.

• Plot random points on the graph and connect them to form a line.

• Use the slope and the x-intercept to find the y-intercept.

How do you graph a line in standard form?

• Rewrite the equation in vertex form and plot the vertex and additional points using the slope.

• Rewrite the equation in standard form and plot the x-intercept and additional points using the slope.

• Rewrite the equation in slope-intercept form and plot the y-intercept and additional points using the slope.

• Rewrite the equation in point-slope form and plot the x-intercept and additional points using the slope.
