Graph x-2y=4

Problem

x−2*y=4

Solution

1. Identify the equation as a linear equation in two variables, which represents a straight line.

2. Solve for y to put the equation into slope-intercept form, y=m*x+b

3. Subtract x from both sides of the equation.

−2*y=−x+4

4. Divide by -2 to isolate y

y=1/2*x−2

5. Identify the slope and y-intercept from the form y=m*x+b where the slope m=1/2 and the y-intercept b=−2

6. Plot the y-intercept at the point (0,−2) on the coordinate plane.

7. Use the slope to find a second point by moving up 1 unit (rise) and right 2 units (run) from the y-intercept to the point (2,−1)

8. Draw a straight line passing through these points to complete the graph.

Final Answer

y=1/2*x−2
