Answer:
y = 7/2x - 5/2 ; gradient is 7/2
y = 5/3x - 4/3 ; gradient is 5/3
y = -2/3x - 10/3; gradient is -2/3
Step-by-step explanation:
2y = 7x-5
- 2y/2 = (7x - 5)/2
- y = 7/2x - 5/2
5x - 3y=4
- (5x-3y) -5x = 4 -5x
- -3y = -5x + 4
- -3y/-3 = (-5x+4)/-3
- y= 5/3x - 4/3
10 - 2x+3y = 0
- (10-2x+3y) -10 = 0 - 10
- -2x + 3y = -10
- (-2x + 3y) + 2x = -10 + 2x
- 3y = 2x -10
- 3y/3 = (2x - 10)/3
- y = 2/3x -10/3
NOTE: The gradient is the slope
