Answer:
The equation of this line would be y = 3/2x - 11, which is the answer D.
Step-by-step explanation:
In order to find this equation we must first find the slope of the original line. The original slope (the coefficient of x) is -2/3, which means the new slope will also be 3/2 because perpendicular lines have opposite and reciprocal slopes. Now, we can use this slope along with the point in point-slope form to find the equation of the line.
y - y1 = m(x - x1)
y - 1 = 3/2(x - 8)
y - 1 = 3/2x - 12
y = 3/2x - 11
One hundred thousand two hundred and three
I would choose to use the equation with feet per hour. Submarines reach such great depths that I feel this unit of measurements better represents the magnitude of those depths.
5x + 2y = 13
x + 2y = 9
-------------------------subtract
4x = 4
x = 1
x + 2y = 9
1 + 2y = 9
2y = 8
y = 4
