the equation of the line is
2x + y = 2
y = -2x + 2
so the slope is,
m = -2
slope of the line perpendicular to this line is
m = 1/2
the two points are (A, -3) and (-2, 4).
also, the slope is
[tex]m=\frac{4-(-3)}{-2-A}[/tex]put m = 1/2
[tex]\begin{gathered} \frac{1}{2}=\frac{7}{-2-A} \\ -2-A=14 \\ A=-2-14 \\ A=-16 \end{gathered}[/tex]so the answer is A = -16
