The equation \( y = -4x + 10 \) defines a linear function. The graph of this equation is a straight line.
- Type of function: Linear function
- Slope: The slope of the line is \(-4\), which indicates that for every one unit increase in \(x\), \(y\) decreases by 4 units.
- Y-intercept: The y-intercept is \(10\), meaning the line crosses the y-axis at the point \((0, 10)\).
In summary, the correct interpretation of the equation is: "This is a linear function. Its graph is a straight line with a slope of -4 and a y-intercept of 10."
