Mathematics for IGCSE & O level - Coordinate Geometry (Section 3 - No. 16)
What is the equation of the line that passes through the point (0, -3) and has a slope of 2?
y = 2x + 3
y = 2x - 3
y = -3x + 2
y = -2x - 3
解释
Using the slope-intercept form (y = mx + c), y = 2x - 3 because the y intercept is -3.
