Write the equation of the line that has an x-intercept of -3 and passes through the point (-3,7)
a. x=-3
b. y=-3
c. y=7

x=-3

Step-by-step explanation:

Answer choice A is a vertical line through the the x-axis crossing through -3. It has an x-intercept of -3.

Answer choice B is a horizontal line through the y-axis crossing through -3. It has no x-intercpet.

Answer choice C is a horizontal line through the y-axis crossing through 7. It has no x-intercept.

Only A has an x-intercept of -3.

step-by-step explanation:

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
