2x-5y+15=0 -5y=-2x-15 y=(2/5)x+3
-3x + 5y = -15At the x-intercept, y=0:-3x = -15 . . . . . x = 5At the y-intercept, x=0:5y = -15 . . . . . y = -3
3xy - 3xy = 0
The x-intercept is (15 0)
-10
5y=25x 25x=5y -5y 25x-5y=0
5y + x = 0 subtract 5y from each side, then x = -5y
x = 0 and y = 4
They are at coordinates of: (0, -6) and (15, 0) respectively
3x - 5y = 45At the y-intercept, x = 0.-5y = 45y = -9At the x-intercept, y = 0.3x = 45x = 15
x=(-5y-1)/3
