The solution to the equation -2x + 4 = -4 is x = 2. This is the x-coordinate of the point where the line intersects the x-axis.
Move the constant term to the right side of the equation.
2x = -8
Divide both sides by the coefficient of x.
x = -4
Locate the x-intercept on the graph.
The x-intercept is the point where the line crosses the x-axis. This happens when y is zero, so we set y to zero and solve for x:
0 = -2x + 4
2x = 4
x = 2
Therefore, the line intersects the x-axis at the point (2, 0).
Plot the point.
Mark a point on the graph at (2, 0).
Draw the line.
Since the slope of the equation is -2 (the coefficient of x), the line will slant downwards from left to right.
