To graph the two equations, let's first rewrite them in slope-intercept form \(y = mx + b\).
1. **Equation 1:** \(y = -3x + 4\)
- This line has a slope of \(-3\) and a y-intercept at \(4\).
2. **Equation 2:** \(y = 3x - 2\)
- This line has a slope of \(3\) and a y-intercept at \(-2\).
### Step 1: Graph the equations
You can visualize the graphs of the equations as follows:
1. **For \(y = -3x + 4\)**:
- Start at the point \((0, 4)\) (y-intercept).
- From there, move down \(3\) units and right \(1\) unit to plot the second point \((1, 1)\).
- Draw the line through these points.
2. **For \(y = 3x - 2\)**:
- Start at the point \((0, -2)\) (y-intercept).
- From there, move up \(3\) units and right \(1\) unit to plot the second point \((1, 1)\).
- Draw the line through these points.
### Step 2: Find the intersection point
Now, let's solve for the intersection of these lines by setting the two equations equal to each other:
\[
-3x + 4 = 3x - 2
\]
Combine like terms:
\[
4 + 2 = 3x + 3x
\]
\[
6 = 6x
\]
Divide both sides by \(6\):
\[
x = 1
\]
Now, substitute \(x = 1\) into either of the original equations to find \(y\):
Using \(y = -3x + 4\):
\[
y = -3(1) + 4 = -3 + 4 = 1
\]
So, the intersection point is \((1, 1)\).
### Conclusion
The two equations graph as follows:
- **Line 1:** \(y = -3x + 4\)
- **Line 2:** \(y = 3x - 2\)
And they intersect at the point marked with a red dot at \((1, 1)\).
If you're graphing these by hand or using graphing software, you can plot the lines and mark the intersection point accordingly.
