Question

Choose the slope-intercept equation of the line that passes through the point shown and is perpendicular to the line shown.



y = 1/3x - 8

y = -3x + 12

y = 3x - 24

y = -1/3x - 4

Answer 1

thats the graph

Answer 2

y=3x-6

Answer 3

it's y = -1/3x - 4

Answer 4

y = -1/3x - 4 Because a slope is perpendicular to another slope if it is the reciprocal of the slope. So 1/3x would be a slope that is perpendicular to 3x. And I knew the y-intercept was -4 because that's where the line would have to pass through to pass through the given point. That's also why the slope is negative, so it would pass through the point.

oh thanks
