SOLUTION: Eliminate the parameter. x = 3t, y = t + 7 choices below y = x divided by three + 7 y = 3x + 7 y = 3x - 7 y = x divided by three - 7

Algebra ->  Trigonometry-basics -> SOLUTION: Eliminate the parameter. x = 3t, y = t + 7 choices below y = x divided by three + 7 y = 3x + 7 y = 3x - 7 y = x divided by three - 7       Log On


   



Question 1137687: Eliminate the parameter.
x = 3t, y = t + 7
choices below
y = x divided by three + 7

x+=+3t,
y+=+t+%2B+7
x+=+3t...........solve for t
x%2F3+=+t
go to y+=+t+%2B+7, substitute t
y+=+x%2F3+%2B+7

from your choices: y = x divided by three + 7
