Which of the following statements is true for a point in the first quadrant of the coordinate plane? A. To graph a point (x, y) in the first quadrant of the coordinate plane, move x units up from the origin and y units to the left.

B. To grab a point (x, y) in the first quadrant of the coordinate plane, move x units to the right of the origin and y units up.

C. To graph a point (x, y) in the first quadrant of the coordinate plane, move x units to the left of the origin and y units up.

C. To graph a point (x, y) in the first quadrant of the coordinate plane, move x units from the origins and Y units to the right.

D. To graph a point (x, y) in the first quadrant of the coordinate plane, move x units up from the origin and y units to the right.

Choice B: Start at the origin. Move units to the right, and units upwards.

Step-by-step explanation:

There are two axes on a typical Cartesian coordinate plane:

Many diagrams of a Cartesian plane would have arrows on these two axis. Typically, there would be:

The arrow on the -axis pointing rightward suggests that as a point move to the right, the coordinate of that point would increase. Conversely, it would be necessary to move points to the right so as to increase their -coordinates.

On the other hand, the arrow pointing upwards on the -axis indicate that as a point move upward, the coordinate of that point would increase. With a similar logic, it would be necessary to move points upward to increase their -coordinates.

Besides, the origin (the intersection of the two axis, unless otherwise specified) would corresponds to . (That is: and .) If the origin is the starting point, it would be necessary to increase the -coordinate by units (by moving rightward units) and increase the the -coordinate by units (by moving upwards units) so as to reach the point .

answer: the answer is 127 degrees

x = -3

y = -18

step-by-step explanation:

to solve by substitution, substitute one variable and solve for the other. then substitute again to find the remaining variable.

x-1/3(3x-9) = -3 since y=3x-9 substittute y.

x-1/3(3x-9)=-3

x + x +3 = -3

2x+3=-3

2x+3-3= -3-3

2x=-6

x=-3

substitute again into y=3x-9

y=3(-3)-9

y=-9-9

y=-18
