Find the value of x and the value of y for which (x, 2) and (8, y) are points on the graph.
-$$y = - 0.5 x + 7$$
A) $x = 10 , y = 10$
B) $x = 10 , y = 3$
C) $x = 3 , y = 3$
D) $x = 3 , y = 10$

To find the value of $x$ when $y = 2$, substitute $y = 2$ into the equation and solve for $x$:$$2 = -0.5x + 7$$$$0.5x = 5$$$$x = 10$$To find the value of $y$ when $x = 8$, substitute $x = 8$ into the equation:$$y = -0.5(8) + 7$$$$y = -4 + 7$$$$y = 3$$Thus, $x = 10$ and $y = 3$, which corresponds to choice B.
