Find the equation of the line that contains points (-2, -9) and is parallel to the line 5X + 7y = 12

5x + 7y = -73

Step-by-step explanation:

In the equation 5x + 7y = 12, the coefficients of x and y determine the slope of the line.  The equation of a line parallel to 5x + 7y = 12 has the same such coefficients, but a different constant (not 12).

Rewrite the given 5x + 7y = 12, replacing the constant (12) by C, and then substitute the coordinates (-2, -9) to determine the new constant:

5(-2) + 7(-9) = C, and so -10 -63 = -73 = C

Finally, the new equation is 5x + 7y = -73.

answer:

it is general formula that is used to write value to its excet position

a11 a12 a13

a21 a22 a23

it is the example of order 2 by 3 matrix in this

a11 means value occur in 1 st row 1st column

a12 means value occurs in 1st row 2nd column

a13 means value occur in 1st row and 3rd column

a21 means value occurs in 2nd row and 1st column

a22 means value occurs in 2nd row and in 2nd column

a23 means value occurs in 2nd row and in 3rd column
