What is the slope of the line graphed below?

The slope of a line is the ratio between the difference of the y coordinates and the x coordinates of two of its points.

In this case, the difference between the y coordinates is 2-1=1

The difference between the x coordinates is -2-3=-5.

So, the slope is

it is contrapositive

i could not see the question too well so check yourself again too . this is because i want you to get it correct.

option (b) is correct

step-by-step explanation:

to find the solution of this system, we need to convert it into reduced row-echelon form. we have,

after applying row operations r2 -> r2/2 and r3 -> r3/3, we get,
