Math Problem Statement
The equation of a line is given below: -12x + 3y = 3. Find the slope and the y-intercept. Then use them to graph the line.
Solution
To solve the given problem, we will:
- Rewrite the equation in slope-intercept form ().
- Identify the slope () and the -intercept ().
- Provide the necessary information to graph the line.
Step 1: Rewrite in slope-intercept form
The equation is:
Add to both sides:
Divide through by 3:
Step 2: Identify the slope and -intercept
From the equation :
- Slope ():
- -intercept ():
Step 3: Instructions to graph
- Start by plotting the -intercept at on the graph.
- Use the slope , which means "rise over run" = . From the point , move up 4 units and to the right 1 unit to plot another point .
- Draw a straight line through the two points.
