A coordinate plane from negative 8 to 8 along the x-axis and from negative 7 to 7 along the y-axis. Which steps should be used t
o graph the equation y – 4 = y minus 4 equals StartFraction one-third EndFraction left-parenthesis x plus 2 right-parenthesis.(x + 2)? 1. Plot the point (2, 4). 2. From that point, count left 3 units and down 1 unit and plot a second point. 3. Draw a line through the two points. 1. Plot the point (2, 4). 2. From that point, count left 1 unit and down 3 units and plot a second point. 3. Draw a line through the two points. 1. Plot the point (–2,4). 2. From that point, count left 3 units and down 1 unit and plot a second point. 3. Draw a line through the two points. 1. Plot the point (–2,4). 2. From that point, count left 1 unit and down 3 units and plot a second point. 3. Draw a line through the two points.
This is the equation of a line in point slope form
where
the point is (-2,4)
the slope is m=1/3
Remember that the formula of slope is "rise over run", where the "rise" (means change in y, up or down) and the "run" (means change in x, left or right)
so
To graph the line
1. Plot the point (–2,4).
2. From that point, count left 3 units and down 1 unit and plot a second point.
