Question

4x - 5y = 2
The graph of the equation above in the xy-plane is a line. What is the x-coordinate of the x-intercept of the line?

The correct answer is: 0.5


    Step by step explanation: 
    Given:
    Equation of line: 4x - 5y = 2
    Step 1:
    Find x intercept:
    Line intersect the x-axis when y-cordinate is zero.
    Step 2:
    Put y = 0 in any 4x - 5y = 2
    ∴ 4x - 5(0) = 2
    ⇒ 4x = 2
    ⇒ x = 2 over 4
    ⇒ x = 1 half
    ∴ the point at which line meets x-axis is (1 half, 0)
    So, the x-intercept of line is 1 half.
