It is -9
y = - 4x - 4
-3x - 9 = 3y -x - 3 = y y = -(x+3)
-4x + 3y = 9
Hey there - First you must put this in y = mx + b (slope intercept format) format, and it will make finding the answers easy. 7x + 3y = -9 3y = -7x - 9 y = -7/3x - 3 Your slope is m, or -7/3 your y intercept is b, or -3 cheers! Donny
It is -9
When the equation is in the form "y = mx + c" the intercept is given by 'c' (and the gradient by 'm'): 3x + 3y = 9 ⇒ x + y = 3 ⇒ y = -x + 3 ⇒ Intercept is 3 (And the gradient is -1)
y = - 4x - 4
At the x-intercept, y = 0 So the equation becomes 4x = -36 or x = -9 So the x-intercept is (-9, 0)
-3x - 9 = 3y -x - 3 = y y = -(x+3)
-4x + 3y = 9

3y = 4x + 9 -4x + 3y = 9 is the standard form
Ok, sure. So:6x-3y-9=0-3y-9=-6x+0-3y=-6x+9y=2x-3
The equation 9=3y has the x-intercept (0,0) and the y-intercept (0,3).
To put the equation 3y - 9 = 2x in y-intercept form (y = mx + b): 3y - 9 = 2x 3y = 2x + 9 (add 9 to both sides of the equation) y = 2/3 x + 3 (divide all terms by 3) The y-intercept is the b term in the equation, which in this example is 3.
3y=4x+9.....-4xAnswer: 4x-3y=9
