Find the value of x and the value of y for which (x, 2) and (8, y) are points on the graph.
-$$y = 3 x + 7$$
A) $x = - 17 , y = - \frac { 5 } { 3 }$
B) $x = - 5 , y = 31$
C) $x = 3 , y = 27$
D) $x = - \frac { 5 } { 3 } , y = 31$

Quizplus · Accepted Answer

To find the value of x when y = 2, substitute y = 2 into the equation and solve for x: $2 = 3x + 7$, which simplifies to $x = -\frac{5}{3}$. To find the value of y when x = 8, substitute x = 8 into the equation: $y = 3(8) + 7$, which simplifies to $y = 31$. Therefore, the correct values are $x = -\frac{5}{3}$ and $y = 31$.
