Answer by drj(1380) (Show Source):
You can put this solution on YOUR website! Use x- and y intercepts to draw the graph for 3x - y = 6
Step 1. The y-intercept occurs when x=0. We have
so we have (0,-6) as one point on the line
Step 2. The x-intercept occurs when y=0. We have
{{x=2}}} so we have (2,0) as another point on the line.
Step 3. Using these points, we can graph as follows:
Solved by pluggable solver: DESCRIBE a linear EQUATION: slope, intercepts, etc |
Equation describes a sloping line. For any
equation ax+by+c = 0, slope is .- X intercept is found by setting y to 0: ax+by=c becomes ax=c. that means that x = c/a. 6/3 = 2.
- Y intercept is found by setting x to 0: the equation becomes by=c, and therefore y = c/b. Y intercept is 6/-1 = -6.
- Slope is -3/-1 = 3.
- Equation in slope-intercept form: y=3*x+-6.

Step 4. Observe the points (2,0) and (0,-6) that are on the line and how it intercepts the axis.
I hope the above steps were helpful.
