The slope perpendicular to the one given is the opposite reciprocal. So the slope of the "new" line will be -1/5. Using y = mx + b and filling in 3 for y, -10 for x and the slope, m, of -1/5 will help you solve for b. Then use that b to write the new equation. 3= -1/5(-10) + b and b = 1. Your equation, then, is y = -1/5x + 1
Volume is area of the triangle multiplied by length:
area = 1/2*base*height
= 1/2*7*2
=7
therefore V = 7*18
= 126
Divide both sides of the equation by - 3
-8x+9y= - 14
-9y+8x=14
simplify the expression
-8x+9y=-14
8x-9y=14
then solve the equation for y
y=-14/9+8/9x
substitute the given value in the ordered pair (x, y)
