Math Problem Statement

Sebuah garis y = 7 - 3xy = 7 - 3x mengalami translasi sejauh 5 satuan ke kiri dan 2 satuan ke bawah, maka bayangan garis tersebut adalah....

Select one:

a. 3x - y - 10 = 3x - y - 10 = 0

b. - 3x + y + 10 = 0 - 3x + y + 10 = 0

C. 3x - y + 10 = 3x - y + 10 = 0

d. - 3x - y - 10 = 0 3x - y - 10 = 0

e. 3x + y + 10 = 3x + y + 10 = 0

Mathematical Concepts

Linear Equations
Translation of Graphs

Formulas

y = mx + b (slope-intercept form of a line)
Translation formulas: x' = x + h, y' = y + k where h is the horizontal shift and k is the vertical shift

Theorems

Translation Theorem: Translating a line does not change its slope, only its position.
