What is the equation of a line that passes through the point (1, 8) and is perpendicular to the line whose equation is y=x2+3 ? Enter your answer in the box
Perpendicular lines' slopes are reciprocals of one another. So we know the perpendicular line will have a slope of 1/2. Then we can use our points to find the rest.
8=1/2(1)+b
8=0.5+b
7.5=b
y=2x+b
