Step-by-step explanation:
Hi there!
<u>Note that</u>:
- Linear equations are typically organized in slope-intercept form:
where m is the slope and b is the y-intercept (the value of y when the line crosses the y-axis) - Perpendicular lines always have slopes that are negative reciprocals of each other (ex. 3 and -1/3, 5/6 and -6/5, etc.)
<u>1) Determine the slope (m)</u>
When we look at the given line,
, we can identify that -2 is in the place of m, the slope of the line. Because perpendicular lines are negative reciprocals of each other, we know that a line perpendicular to this would have a slope of
. Plug this into
:

<u>2) Determine the y-intercept (b)</u>

Plug in the given point (1,-2)

Subtract 1/2 from both sides

Therefore, the y-intercept of the line is
. Plug this back into 

I hope this helps!
