Solving and Graphing Linear Equations Review

What is the first step in graphing a linear equation in slope-intercept form?

• Find the slope

• Draw the line

• Plot the y-intercept

• Plot the x-intercept

In point-slope form, what does the point (x1, y1) represent?

• The slope

• The y-intercept

• The x-intercept

• A point on the line

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

• Set y to zero and solve for x

• Set x to zero and solve for y

• Plot the y-intercept

• Find the slope

What should you do if one of the intercepts is not an integer in standard form?

• Plot it as a fraction

• Use a different method

• Convert to slope-intercept form

• Ignore it

What is the slope of the line represented by the equation y = 4x + 10?
