Mathematics for IGCSE & O level - Coordinate Geometry (Section 4 - No. 38)
What are the gradient and y-intercept of the line represented by the equation 4x - 2y = 8?
Gradient = 2, y-intercept = -4
Gradient = -2, y-intercept = 4
Gradient = -2, y-intercept = -4
Gradient = 2, y-intercept = 4
설명
Rearrange to slope-intercept form (y = mx + c): -2y = -4x + 8, y = 2x -4. Gradient = 2, y-intercept = -4
