The correct interpretation of the equation \( y = -4x + 10 \) is as follows:

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 slope-intercept form \( y = mx + b \), where \( m \) is the slope and \( b \) is the y-intercept. This confirms it is a linear function.
  • Slope: The slope \( -4 \) indicates that for every unit increase in \( x \), \( y \) decreases by \(4\). This means the line is decreasing.
  • Y-Intercept: The y-intercept \( 10 \) means that 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."
