Answer:
Step-by-step explanation:
The equation y=−2x+9y=−2x+9 represents a straight line in the Cartesian coordinate system. In this equation:
The coefficient of x is −2, indicating that the line has a slope of −2.
The constant term 9 is the y-intercept, meaning the line crosses the y-axis at the point (0, 9).
The equation describes a line that slopes downward at a rate of 2 units for every 1 unit it moves to the right. The y-intercept suggests that the line intersects the y-axis at the point (0, 9).
Simple way of remembering is the number before X is gradient and the other number is y intercept
