A plot of two planes drawn in blue and green. The blue plane increases the z-coordinate with an increase in y-coordinate or decrease in the x-coordinate. The green plane increases the z-coordinate when either the x or y-coordinate decreases. Along the line where the green and blue planes intersect, there are three arrows starting at the midpoint. The blue arrow moves in the negative x, positive y, and positive z direction and is perpendicular to the blue plane. The blue arrow is labeled
\(\langle -2,1,-3 \rangle\text{.}\) The green arrow moves in the positive x, y, and z directions and is perpendicular to the green plane. The green arrow is labeled
\(\langle 1,2,1 \rangle\text{.}\) The red arrow moves in the positive x, negative y, and negative z direction and is perpendicular to the blue plane. The red arrow is labeled
\(\langle 1,-0.5,1.5 \rangle\text{.}\)
