What is the slope of the line graph below?
a)-1/2
b)1/2
c)1
d)2

D) 2

Step-by-step explanation:

If we look at the graph we can see that it has the points :

(0,1) and (1,3)

Since it's a linear equation the slope is the same throughout the graph so we can evaluate the slope from these 2 points.

The formula fro calculating slope is rise/run

In other words,

Where x1 = 0, x2 = 1, y1 = 1, y2 = 3

So slope  =

So the answer is 2

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
