Perpendicular would have a slope of 1/8 and a line paralell to y=-8 would be y=-8+5 because they have the same slope but different y-intercepts.
The slope intercept form of equation of required line is y = 3x + 9
What is equation of line in slope intercept form?
The most general form of equation of line in slope intercept form is given by y = mx + c
Where m is the slope of the line and c is the y intercept of the line.
Slope of a line is the tangent of the angle that the line makes with the positive direction of x axis.
If
is the angle that the line makes with the positive direction of x axis, then slope (m) is given by
m = 
The distance from the origin to the point where the line cuts the x axis is the x intercept of the line.
The distance from the origin to the point where the line cuts the y axis is the y intercept of the line.
Here,
Slope = 3
The line passes through (8, 33)
Equation of required line
y - 33 = 3(x - 8)
y - 33 = 3x - 24
y = 3x - 24 + 33
y = 3x + 9

2.; it’s the easiest, fastest, and simplest way to get to your factors
Since we are dealing with VOLUME, when you increase an amount, we CUBE the difference. 2^3 = 8
The sphere that has 2 times the radius has 8 times the volume.
