Question

Which equation can be represented by the graph shown on the grid?

a. 9x+2y=9
b. 2x+9y=9
c. 9x-2y=9
d. 2x-9y=9​

Answer 1

c

Explanation:

Answer 2

• c. 9x - 2y = 9

Explanation:

As per the graph, the line has:

• y-intercept (0, -4.5)
• x-intercept (1, 0)

Substitute the values and verify each equation.

This gives us one correct equation:

• 9x - 2y = 9

Proof:

• x = 0 ⇒ -2y = 9 ⇒ y = -4.5
• y = 0 ⇒ 9x = 9 ⇒ x = 1
