The equation \( y = -4x + 10 \) defines a linear function.
Interpretation:
- Type of Function: Linear function
- Graph Description: The graph is a straight line.
- The slope is \(-4\), indicating that for every unit increase in \(x\), \(y\) decreases by 4 units.
- The y-intercept is \(10\), which means the line crosses the y-axis at the point \((0, 10)\).
Thus, the correct response is: This is a linear function. Its graph is a straight line with a slope of -4 and a y-intercept of 10.
