Practice problem
Write an equation for a line perpendicular to h(t)=−2t+4h(t)=-2t+4h(t)=−2t+4 and passing through the point (−4,−1)(-4,-1)(−4,−1).
y=12x−1y=\frac12 x-1y=21x−1
y=12x+1y=\frac12 x+1y=21x+1
y=12x+2y=\frac12 x+2y=21x+2
y=12x+3y=\frac12 x+3y=21x+3
Type a concept, like “slope” or “photosynthesis”.
