Awalking path across a park is represented by the equation y=-2x+5. a
new path will be built perpendicular to this path. the paths will intersect at
the point (-2,9). identify the equation that represents the new path.
a. y= {x+10
b. y= -2x - 5
c. y= 2x+13
d. y -- 1x+8

Step-by-step explanation:

The given path is:

y = -2x+5

Comparing with the standard form of equation:

y = mx+b

So,

m = -2

We know that product of slopes of two perpendicular lines is -1

Let m1 be the slope of the perpendicular line

m*m1=-1

-2*m1 = -1

m1 = -1/-2

m1 = 1/2

So the slope of perpendicular path is 1/2.

Since the new path passes through (-2,9)

Putting the values of m and b in standard form

Hence the equation of new path is:

..

the entire expression should be subtracted from 30. to subtract the quantity, distribute the negative sign, which changes the signs on the terms. so, the –2 changes to positive and gets added to 30 instead of subtracted from it.

hope this ! ^w^
