y = 2/3x + 5....slope here is 2/3...so the line is increasing...going up....the 5 in the equation is ur y int, where the line crosses the y axis....so this equation will be line 4
y = x - 3....slope is 1....increasing....y int is -3....this is line 1
y = -3/4x + 3....slope is -3/4.....this one is decreasing...going down...the y int is 3....so this is line 2
y = -1/2x - 4....slope is -1/2...so this is decreasing...y int is -4...so this one is going to be line 3
