If triangle abc is reflected over the y-axis, which of the following shows the coordinates for point c'?

(3, 7)
(3, −7)
(−3, 7)
(−3, −7)

(-3,7)

Step-by-step explanation:

From the given graph , the coordinates of point C in the triangle ABC = (3,7) .

When a figure reflected over the y-axis the , the rule to determine coordinates of the image is given by :-

, i.e. only the sign of the x-coordinate changes .

If triangle ABC is reflected over the y-axis, then the coordinates for point C' will be :

Hence, the coordinates for point C'= (-3,7)

Therefore , the correct option is (-3,7) .

solution:

→c= a b , that is product of a and b is possible only when when a is m × n matrix and b is n × p matrix.

that is, number of columns of a= number of rows of b.

so, size of matrix , c= a b is , if a = (m × n)matrix

b= (n × p)matrix

then a b = [ (m × n)matrix] ×[   (n × p)matrix ]

→→c= a b= [m × p ] matrix

→→size of product a b will be equal to = number of rows of a × number of columns of b
