Write the equation 6x − 3y = −12 in the form y = mx + b.

3y = 6x + 12
y = 2x + 12
y = 2x + 4
y = 2x − 4

last option

step-by-step explanation:

given that δdef is right and isoceles,

assuming that side df is the hypotenuse means that de an ef are the other 2 sides that intersect at 90° and are of equal length.

because they are of equal length, we can say that they are congruent

because they intersect at 90°, their slopes must be opposite reciprocals.

only the last option satisfies these conditions.
