What lines are perpendicular to 2x-7y=-25

Step-by-step explanation:

Given the line 2x-7y = -25

First let us get the slope of the line:

Rewrite the equation in the form y = mx+c

2x-7y = -25

-7y = -2x-25

y = -2x/-7-25/-7

y = 2/7 x +25/7

The slope of the line is 2/7

Ffor two lines to be perpendicular, the product of their slope must be -1

mM = -1

m(2/7)= -1

2m = -7

m = -7/2

Hence the lines perpendicular to the given line must be a line that has a slope of -7/2. Since we are not given option, we can say example of such line is y = -7/2 x + 15

the answer is 489
