Math Problem Statement
Graph the line represented by the equation 3x + 4y = 12. Select two points on the coordinate grid to represent the x- and y-intercepts. A line will connect the points.
Solution
The equation in the image is . To graph this, let's find the intercepts and use them to plot the line.
Finding the intercepts:
-
For the x-intercept: Set in the equation . So, the x-intercept is .
-
For the y-intercept: Set in the equation . So, the y-intercept is .
Plotting:
- The x-intercept is .
- The y-intercept is .
To graph the line, plot these two points and on the grid and connect them with a straight line.
