Question

Choose the option which describes the equation of the line shown in the graph.

• A. y = x + 4
• B. y = 2x
• C. x + y = 0
• D. y = 2x + 4

Answer 1

The correct option is D y = 2x + 4

Substitute the values of x and y from given points in the graph in the equations options. Start putting these values in the given options. The equation which is satisfied by these values is the equation of the line on the graph.
y = 2x + 4
at x = 1, y = 6
at x = 0, y = 4
at x = -2, y = 0
∴ Graph of equation y = 2x + 4 is shown in the figure.
