Which system of equations is represented by the matrix below? [2 -3|8]
[5 0|10]

A. 2y - 3x = 8
5y = 10

B. 3x - 2y = 8
5x = 10

C. 2x - 3y = 8
5x = 10

C

Step-by-step explanation:

the x,y matrix will have the form of some x coefficient value, some y coefficient value and then the answer. if one of these values are missing you use a 0 as placeholder. look at the coefficients here. you know one equation will have an x coefficient of 2 and a y coefficient of -3 with a solution of 8 and the other equation will have x coefficient of 5 and no y at all with a solution of 10. only option c meets these criteria

for this case we have by definition, if two lines are perpendicular, then the product of their slopes is -1.

then, given the following line:

so,

we are looking for m_ {2}:

then, the line is given by:

we find "b" replacing the given point:

finally, the equation is:

option c

6e14 is the answer.
