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
G(x)=3(x-2)
g(x)=3(x-2)=6
solve for x in
3(x-2)=6
divide both sides by 2
x-2=2
add 2 to both sides
x-2+2=2+2
x=4
1/2 * 1 * (1 + 1) = 1
1/2 * 2 * (2 + 1) = 3
1/2 * 3 * (3 + 1) = 6
1/2 * 4 * (4 + 1) = 10

Answer:
y=(7/4)x + 12, y=(-4/7)x -46/7
Step-by-step explanation:
first for the perpendicular line: we know the slope is the opposite reciprocal of -4/7, so m= 7/4. now we have y= 7/4 x +b. b is the y-intercept. to find b plug in the point (-8,-2). -2=(7/4)(-8) + b = -14+b so b=12. so the slope of the perpendicular line is y=(7/4)x + 12
parallel:
since the line is parallel the slope is -4/7. so we have y=(-4/7)x + b. next plug in the point (-8, -2) to find b: -2 = (-4/7)(-8) + b = 32/7 + b. so b= -46/7
