Mathematics for IGCSE & O level - Coordinate Geometry (Section 3 - No. 28)
Which of the following is true about the equation 2x - y + 3 = 0?
The y-intercept is 3.
The gradient is 2.
The y-intercept is -3.
The gradient is -2.
Penjelasan
Rearrange to slope-intercept form (y = mx + c): y = 2x + 3. The gradient is 2.
