straight variation explains a straightforward relationship in between two variables . We say y varies straight v x (or together x , in some textbooks) if:
y = k x
for part consistent k , called the continuous of variation or consistent of proportionality . (Some textbooks describe direct sport by saying " y varies straight as x ", " y varies proportionally as x ", or " y is directly proportional come x .")
This way that as x increases, y increases and as x decreases, y decreases—and the the proportion between them constantly stays the same.
The graph of the direct variation equation is a directly line v the origin.

| straight Variation Equation because that 3 various values the k instance 1: provided that y varies straight as x , through a constant of sports k = 1 3 , uncover y once x = 12 . compose the direct variation equation. y = 1 3 x substitute the given x value. y = 1 3 ⋅ 12 y = 4 example 2: offered that y varies straight as x , discover the consistent of sport if y = 24 and x = 3 . create the direct variation equation. y = k x substitute the given x and y values, and solve because that k . 24 = k ⋅ 3 k = 8 example 3: expect y varies straight as x , and y = 30 as soon as x = 6 . What is the value of y as soon as x = 100 ? create the direct variation equation. y = k x instead of the offered x and also y values, and solve because that k . 30 = k ⋅ 6 k = 5 The equation is y = 5 x . Now substitute x = 100 and also find y . y = 5 ⋅ 100 y = 500 Subjects near Me plot Tutors ARRT check Prep Spanish Lessons collection 26 test Prep collection 32 test Prep worldwide Health plan Tutors series 53 check Prep 5th Grade math Tutors USMLE test Prep Louisiana Bar Exam courses & class Rhode Island Bar Exam courses & classes PCAT writing Tutors series 65 check Prep Michigan Bar Exam courses & classes LSW - Licensed social Worker courses & classes Actuarial test FM test Prep series 6 courses & classes LSAT check Prep NAPLEX - nationwide Association boards of Pharmacy check Prep Bar review Tutors Popular Cities Phoenix Tutoring Washington DC Tutoring Salt Lake City Tutoring ras Vegas Tutoring Syracuse Tutoring Nashville Tutoring Sacramento Tutoring Atlanta Tutoring Oklahoma City Tutoring Orlando Tutoring Popular Subjects English Tutors in Los Angeles Chemistry Tutors in Phoenix French Tutors in Houston biological Tutors in Houston GRE Tutors in Chicago MCAT Tutors in Atlanta Spanish Tutors in brand-new York City Physics Tutors in Dallas fort Worth GRE Tutors in san Diego French Tutors in san Francisco-Bay Area Download our free learning tools apps and test prep booksShow More Varsity Tutors Our Company Free Resources Top Subjects Top Locations Show legit DisclaimerHide legal DisclaimerPrivacy PolicyTerms that UseSitemapSign In Names of standardization tests are owned through the trademark holders and also are not affiliated through Varsity Tutors LLC. *See complete details for better Score Guarantee.
