Which of the following is true about the line represented by the equation 2x - 3y = 6?
The gradient is 2/3.
The y-intercept is -2.
The x-intercept is 3.
The line passes through the origin.
Spiegazione
Rearrange to slope-intercept form: -3y = -2x + 6 => y = (2/3)x - 2. Gradient = 2/3, y-intercept is -2, x-intercept is 3 (when y=0).
