If two lines are perpendicular, the slope of one of the lines is the negative reciprocal of the other. Since we know the slope for one of our lines, m lets find the other:
Now, lets use the point-slope formula to complete the equation of our perpendicular line:
Surface area is 34 units2 or sq. the volume is 10 units3 or cubed. volume is the amount of cubes on the inside, and the surface area is each surface added together
