Ok, I need help with this question, I've wasted so many points already and I've gotten nowhere Its in the speed and velocity section in science, grade 8.

1. (1,2)

2.(4,8)

In this problem you are trying to find slope, so this is fairly simple.

You do y2-y1/x2-x1

so simplified its

8-2/ 4-1

6/3

so your slope is

2 or 1/2

Also brainliest is always welcomed.

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
