Answer:
x = 2
y = - z (for example 2)
Step-by-step explanation:
2³+2³+(-2)³= 8+8-8=8
Answer:
The perpendicular line would be y = -2/3x - 9
The parallel line would be y = 3/2x + 21/2
Step-by-step explanation:
Since we have the slope of 3/2, we know the perpendicular slope will be -2/3. This is because perpendicular lines have opposite and reciprocal slopes. Now we can use that and the point in point-slope form to get the equation.
y - y1 = m(x - x1)
y + 3 = -2/3(x + 9)
y + 3 = -2/3x - 6
y = -2/3x - 9
For the parallel line we would use the same slope as the original (3/2) and also start with point-slope form.
y - y1 = m(x - x1)
y + 3 = 3/2(x + 9)
y + 3 = 3/2x + 27/2
y = 3/2x + 21/2
