To graph the linear equation \( y = -6x - 4 \), we can find some key points by substituting values for \( x \) and calculating the corresponding \( y \) values.
-
Find y-intercept: Set \( x = 0 \): \[ y = -6(0) - 4 = -4 \] So the point is \( (0, -4) \).
-
Find another point: Set \( x = 1 \): \[ y = -6(1) - 4 = -6 - 4 = -10 \] So the point is \( (1, -10) \).
Now we have two points: \( (0, -4) \) and \( (1, -10) \).
- Find a third point for more accuracy: Set \( x = -1 \): \[ y = -6(-1) - 4 = 6 - 4 = 2 \] So the point is \( (-1, 2) \).
Now we can plot the points \( (0, -4) \), \( (1, -10) \), and \( (-1, 2) \) on the coordinate plane.
- The line connecting these points will have a negative slope, indicating that as \( x \) increases, \( y \) decreases.
Summary of the graph characteristics:
- The line passes through the points \( (0, -4) \) and \( (1, -10) \).
- The line is downward sloping.
Checking the options given, the correct answer is:
- An illustration of a coordinate plane with four quadrants shows the x-axis ranging from negative 9 to 9 and the y-axis ranging from negative 11 to 11 in increments of 1. A solid downward line with arrows at both ends is plotted on the graph. The line passes through the plotted points \( (0, -4) \) and \( (1, -10) \).
