Question

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

Answer 1

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

Answer 2

After adding everything together you should get y=-2x+10
