As stated in the strategy, choose a coordinate system where the x axis is horizontal and the y axis is vertical. note that in the strategy, the y component of the projectile's acceleration, ay, is taken to be negative. this implies that the positive y axis is upward. use the same convention for your y axis, and take the positive x axis to be to the right. where you choose your origin doesn't change the answer to the question, but choosing an origin can make a problem easier to solve (even if only a bit). usually it is nice if the majority of the quantities you are given and the quantity you are trying to solve for take positive values relative to your chosen origin. given this goal, what location for the origin of the coordinate system would make this problem easiest?

the system of inequity is

step-by-step explanation:

from the given graph it is noticed that we have two related lines. one is solid and another is dashed.

if a line passing through two points, then the equation of line is

the solid line passing through the points (0,4) and (4,0).

the related equation of solid line is .

similarly, find the related equation of dashed line. the dashed liune passing through the points (0,0) and (3,1).

the related equation of dashed line is

from the given graph it is noticed that the point (0,1) lies on the shaded region, therefore the point (0,1) must be satisfied by the related equations.

check the related equations by the point (0,1).

this statement is true if the sign of inequality is < instead of equality. since it is an solid line therefore the sign of inequality will be . the required inequality is

similarly, check the second related equation.

it is a dashed line, so this statement is true if the sign of inequality is > . the required inequality is

c) yes, because of asa or aas
