Ms. Khan asked her math students to find an equation of a line which has a graph parallel to the line y - 2+1 and which passes through the point (4,-2).
Which equation is correct?

Step-by-step explanation:

i will assume u mean y - 2x+1

y = 2x-1

parallel lines have the same slope (m) = x coefficient = 2

line general equation = y = mx + b

y = 2x + b

from the point given (4,-2)

x=4. y = -2

-2 = 2×4 +b

-2 = 8 + b

b = -10

y = 2x -10

if it is not y-2x +1

plz tell me

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.

i dont get the question
