What is the equation of the function that is graphed as line a

Step-by-step explanation:

From the graph we have:

y-intercept = -1

x-intercept = -1

The slope-intercept form of an equation of a line:

y = mx + b

m - slope

b - y-intercept

Therefore we have: y = mx - 1

Put the coordinates of the x-intercept to the equation:

(-1, 0) → x = -1 and y = 0:

0 = -1m - 1       add m to both sides

0 + m = -m + m - 1

m = -1

Finally we have the equation:

y = -1x - 1

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
