Math Problem Statement
Graph 2x+3y=6
Solution
To graph the equation , follow these steps:
Step 1: Write the equation in slope-intercept form
First, solve the equation for in terms of .
Subtract from both sides:
Now, divide every term by 3 to solve for :
Step 2: Identify the slope and y-intercept
From the slope-intercept form , we can identify:
- The slope
- The y-intercept
Step 3: Plot the y-intercept
Start by plotting the y-intercept on the graph.
Step 4: Use the slope to find another point
The slope means that for every 3 units you move to the right (positive direction on the x-axis), you move 2 units down (negative direction on the y-axis). Starting from the y-intercept :
- Move 3 units to the right to .
- Move 2 units down to .
So, another point on the line is .
Step 5: Draw the line
Plot the points and on the graph, and then draw a straight line through these points.
