a line whose perpendicular distance from the origin is 4 units and the slope of perpendicular is 2÷3. Find the equation of the line.

Step-by-step explanation:

The equation of a line:

We have

substitute:

The formula of a distance between a point and a line:

General form of a line:

Point:

Distance:

Convert the equation:

    |subtract from both sides

   |multiply both sides by 3

Coordinates of the point:

substitute:

   |multiply both sides by

  |divide both  sides by 3

Finally:

24

step-by-step explanation:

the graph shows 30% of students walk. 80 students were questioned, so the number that said they walk is

30% × 80 = 0.30 × 80 = 24
