To graph the equation \(y = 14x + 2\), follow these steps:
Step 1: Identify the Slope and Y-Intercept
The equation is already in slope-intercept form \(y = mx + b\), where:
- \(m\) (slope) = 14
- \(b\) (y-intercept) = 2
This means the line crosses the y-axis at \( (0, 2) \).
Step 2: Plot the Y-Intercept
- Start by plotting the point \( (0, 2) \) on the graph. This is where the line crosses the y-axis.
Step 3: Use the Slope to Find Another Point
The slope of the line is 14, which can be interpreted as:
- For every 1 unit you move to the right (increase in \(x\)), you move up 14 units (increase in \(y\)).
Starting from the y-intercept \( (0, 2) \):
- Move 1 unit to the right to \( (1, 2) \).
- Move up 14 units to reach \( (1, 16) \).
Step 4: Plot the Second Point
- Plot the point \( (1, 16) \).
Step 5: Draw the Line
With the two points \( (0, 2) \) and \( (1, 16) \) plotted:
- Draw a straight line through these points and extend it in both directions with arrows on each end.
Additional Points for Accuracy
You can calculate additional points by plugging in values for \(x\) and solving for \(y\):
-
If \(x = -1\):
\[
y = 14(-1) + 2 = -14 + 2 = -12 \quad \text{→ Point} (-1, -12)
\]
-
If \(x = 2\):
\[
y = 14(2) + 2 = 28 + 2 = 30 \quad \text{→ Point} (2, 30)
\]
Final Note
With these points, you can accurately graph \(y = 14x + 2\). If using graphing software or graph paper, make sure to label the axes appropriately and extend the line beyond the plotted points. The line will rise steeply due to the high slope of 14.
