Question

Which of the following statements best describes the graph of x + y = 3?

a) It is a line joining the points whose X- and y-coordinates add up to 3.
b) It is a line joining the points whose X- and y-coordinates add up to 6.
c) It is a line which intersects the x-axis at (3, 3).
d) It is a line which intersects the y-axis at (3, 3).

Answer 1

The equation x + y = 3 represents a line on a graph. By considering different values of x and y that satisfy the equation, you can plot points and create a line.

Step-by-step explanation:

The equation x + y = 3 represents a line on a graph. In this equation, the coefficients of x and y are both 1. To find the graph, you can consider some points that satisfy the equation and plot them on the graph. For example, when x = 0, y = 3, and when y = 0, x = 3. By connecting these points, you will get a line.
