Write an equation of a line perpendicular to
y = 2/7x - 5 through (2, -3)

Hi there! :)

Given equation:

y = 2/7x - 5

A perpendicular line will have a slope that is the opposite reciprocal, therefore:

2/7 --> -7/2

Substitute the x and y coordinates of the point given to write an equation in slope-intercept form:

(-3) = -7/2(2) + b

Simplify:

-3 = -7 + b

-3 + 7 = b

b = 4

Rewrite the equation:

y = -7/2x + 4

After studying children who watched  hours of television after school, one

researcher found that watching  several hours of television every  day was often linked to childhood  obesity and lack of physical activity.  Childhood obesity is a "complicated  and sociopolitical issue," and parents,  teachers, community leaders, and  governmental leaders can work  together to encourage youth to  make healthier decisions.  As childhood obesity rates continue  to be rise, scientists believe  that one important factor in  making a difference will be  “educating families, especially  in poverty-stricken areas”
