Which equation represents a line that is perpendicular to y=2/5x +1 and passes though (-10,20)

the answer is 48m^2!

step-by-step explanation:

the formula of a slope:

we have the points (-2, 7) and (2, 3). substitute:

in mathematics, a constraint is a condition of an optimization problem that the solution must satisfy. there are several types of constraints—primarily equality constraints, inequality constraints, and integer constraints. the set of candidate solutions that satisfy all constraints is called the feasible set.

hoped i'm right lol
