1. Problem Description
The problem is to graph the linear equation .
2. Solution Steps
To graph the equation , we can find two points on the line and then draw the line through those points. We can find the intercepts.
To find the -intercept, set and solve for :
So, the -intercept is or .
To find the -intercept, set and solve for :
So, the -intercept is .
We can plot the points and on the graph and draw a line through them.
Alternatively, we can rearrange the equation to slope-intercept form: , where is the slope and is the -intercept.
The -intercept is , which means the line passes through . The slope is . This means that for every 7 units we move to the right, we move 4 units down. So, starting from , we can move 7 units to the right and 4 units down to reach the point .
