Respuesta :
-3(x+3y)=5
-3x -9y =5
-9y=5+3x
y=-5/9 -(3/9)x
y = (-1/3)x-5/9
Slope = -1/3, y-intercept is (0, - 5/9)
-3x -9y =5
-9y=5+3x
y=-5/9 -(3/9)x
y = (-1/3)x-5/9
Slope = -1/3, y-intercept is (0, - 5/9)
You said: -3(x+3y) = 5
Multiply each side by -1 : 3(x + 3y) = -5
Eliminate the parentheses on the left: 3x + 9y = -5
Subtract 3x from each side: 9y = -3x - 5
Divide each side by 9 : y = -1/3 x - 5/9
There's your slop-intercept form.
Slop = -1/3
Intercept = -5/9
