The equation for point-slope form is

m being the slope, y1 being the second point in the (2, -6) and the x1 being the first point in the (2, -6).
So the equation would look like this (for point-slope):

If you're looking for slope-intercept form you can simplify the equation:

If you're looking for the standard form of the equation, you can take the slope-intercept equation and turn it into standard form:
Answer:
12x<180
14
Step-by-step explanation:
12x<180
x<180/12
x<15
Since x has to be less than 15, he took at most 14 people.
Answer:
201.06
Step-by-step explanation:
A=4πr2 is the equation (r being radius)
4·π·(4)2≈201.06193
