Find the slope of the line that passes through the points (2, 1) and (-4, -5).

slope is 1

Step-by-step explanation:

use the slope formula

m=(1+5)/(2+4)

m=6/6

m=1

slope is 1

Step-by-step explanation:

use the slope formula

m=(1+5)/(2+4)

m=6/6

m=1

according to the triangle sum theorem, all the angles in a triangle must add up to 180 degrees. if we know one angle is already 90, we do 180-90=90. the other 2 angles must add up to 90, exactly.

step-by-step explanation:

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,
