Question

What is the equation of the line perpendicular to y=-1/3x+-4 through the point ( 3,8)? ​

Answer 1

Answer: y=3x-1

Explanation:

If it’s perpendicular, the slope is the opposite reciprocal so we have:

y=3x+b

Use the point to find b

8=3(3)+b

8=9+b

Subtract 9 on both sides

B=-1

y=3x-1
