Answer:

Step-by-step explanation:

The points given are: (1,-4), (7,-7), (13,-10), (19,-13)

They line up to a straight line with slope:

((-4)-(-7))/(1-7) = 3/-6 = -1/2

The equation in point-slope form is

(y-(-4)) = -1/2(x-1)

y+4 = -1/2(x-1)

A is the right answer.

Answer:

Step-by-step explanation:

there is a linear relationship

from the table, x changes by +6, y changes by -3 every time

so that means the slope is constant i.e. its a straight line

slope=(y2-y1)/(x2-x1)=-3/6

= -1/2

take the 1st pt, ( 1, -4 )

(y-(-4)) = slop * (x-1)

y+4 = -1/2*(x-1)

ans is A

The coordinates of point A on a coordinate grid are (−2, −3). Point A is reflected across the y-axis to obtain point B and acros
amid [387]

Answer:

B) B(2,-3) and C(-2,3)

Step-by-step explanation:

The given point A, has coordinates (-2,-3).

When point A(-2,-3) is reflected over the y-axis to obtain point B, then the coordinates of B is obtained by negating the x-coordinate of A.

Therefore B will have coordinates (2,-3).

 When point A(-2,-3) is reflected over the x-axis to obtain point C, then the coordinates of C is obtained by negating the y-coordinate of A.

Hence the coordinates of C are (-2,3)

How do you find magnitude of a vector
Otrada [13]
Draw a vector triangle. When you draw the horizontal and vertical components, you end up with a right triangle. The magnitude of the vector is equal to the hypotenuse of the triangle so you can use the Pythagorean theorem to calculate it. Rearrange the Pythagorean theorem to calculate the magnitude
