Answer:
y = 1/2x + 3
Explanation:
first we change the first equation to slope-intercept form to find the reciprocal slope
2y - 4x = -10
add 4x to both sides
2y = 4x - 10
divide both sides by 2
y = 2x - 5
since perpendicular lines have reciprocal slopes the slope of our new line is 1/2
y = 1/2x + b
to find b we plug in the point
1 = 1/2(-4) + b
1 = -2 + b
add 2 to both sides
3 = b
___
our new line is
y = 1/2x + 3
