Please HELP me 50 points worth

y=-½x + 1

Step-by-step explanation:

1.) a perpendicular lines uses the opposite inverse of a line so the slope becomes -½x

2.) make an equation that looks as so:

y=-½x+b

the y intercept is unknown so it must be a variable.

3.) substitute the points you are given into the equation:

3=-½(4)+b

4.) solve for b

3=2+b

-2|-2

1=b

4.) place b into the equation

y=-½x + 1
