The correct interpretation of the equation \( y = -4x + 10 \) is:
This is a linear function. Its graph is a straight line with a slope of -4 and a y-intercept of 10.
Explanation:
- Type of Function: The equation is in the form \( y = mx + b \), where \( m \) represents the slope and \( b \) represents the y-intercept. Since it follows this linear form, it is classified as a linear function.
- Slope: The slope is -4, indicating that for each increase of 1 unit in \( x \), the value of \( y \) decreases by 4 units. This means the line descends as it moves from left to right.
- Y-intercept: The y-intercept is 10, which indicates that the line crosses the y-axis at the point (0, 10).
Graph:
- This function's graph will be a straight line that starts at (0, 10) and moves downward due to the negative slope of -4. As \( x \) increases, \( y \) decreases, making the line slant downwards.
Therefore, the first option correctly describes the function and its graph.
