Answer:
y=2x-7
x+2y=3
Step-by-step explanation:
The equation y=2x-7 has slope m=2
The equation x+2y=3 can be rewritten in the slope intercept form to get;
[tex]y=-\frac{1}{2}x+\frac{3}{2}[/tex]
The slope of this equation is
[tex]m=-\frac{1}{2}[/tex]
The first slope is the negative reciprocal of the second hence the two lines are perpendicular.
The correct choice is A
