Answer

Plot the points (2, -3) and (9, -1) on a coordinate plane and draw a straight line through them.

Solution

  1. Start with the given equation in point–slope form:
  2. Identify the fixed point and the slope.
    From the equation, the line passes through the point
    and has a slope of
  3. To plot two points, use the known point and find another point by using the slope.
    Since the slope is , it means that for an increase of in , increases by .
    Starting from :
    • Increase by : .
      Then,
    So, the second point is .
  4. Alternatively, you can verify by converting the equation to slope–intercept form:
    Express as :
    The y-intercept is . However, plotting and from the step–slope form is generally simpler.
  5. Finally, plot the points and on a coordinate plane and draw a straight line through them, which represents the graph of the equation.
Thus, the two points to plot are:

Bonus Knowledge

To graph the equation , let’s first rewrite it in slope-intercept form . Start by rearranging the equation:
  1. Subtract 3 from both sides:
  2. Distribute the :
  3. To combine terms, convert -3 to a fraction:
Now, let’s plot two points.
Point 1: When :
So, the first point is .
Point 2: When :
So, the second point is .
With points and , you can now plot these on a graph and connect them to create a line!
