Mathematics for IGCSE & O level - Coordinate Geometry (Section 4 - No. 36)
Which of the following statements are true about the equation 4x + 3y = 12?
The gradient is -4/3.
The y-intercept is 4.
The x-intercept is 3.
The line passes through the point (1, -3).
Paliwanag
Rewrite as y = -4/3 x + 4 The gradient is -4/3 and the y intercept is 4. When setting x=0, y=4 and when setting y=0, x=3
