What is an equation of the line that passes through the point (-1, -3) and is perpendicular to the line y=1/2x-7 ?
1 answer:
Answer:
y = -2x - 5
Step-by-step explanation:
Set the slope of the given equation to the reciprocal to get a perpendicular slope:
y = 1/2x --> -2x
y = -2x + b will be your current equation. To get b, you must insert the given information: (-1, -3)
-3 = -2 (-1) + b
Solve:
-3 = 2 + b
<u>-2 -2 </u>
-5 = b
Thus your equation would be y = -2x - 5.
