The graph of the equation y=3x+4 is shown. Determine the value of y for the point (-1, y)
A. -2
B. -1
C. 0
D -1

The answer is positive 1

Step-by-step explanation:

At x=-1, the graph's y-coordinate is 1

1

Step-by-step explanation:

Here, we know that the x value is -1, so we substitute it in the equation.

Hope this helps :-)

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
