1. Problem Description
The problem asks to find the x and y intercepts of the equation and then sketch the graph of the equation.
2. Solution Steps
First, we need to find the x-intercept. The x-intercept is the point where the graph crosses the x-axis, meaning .
Substitute into the equation :
So, the x-intercept is .
Next, we need to find the y-intercept. The y-intercept is the point where the graph crosses the y-axis, meaning .
Substitute into the equation :
So, the y-intercept is .
Now that we have the x and y intercepts, we can sketch the graph. We have two points: and . We can plot these points on the coordinate plane and draw a straight line that passes through both points.
3. Final Answer
x-intercept:
y-intercept:
The equation of the line is . The graph is a straight line passing through and .
