Answer:
If the line is gonna be perpendicular then the slope going to be the inverse opposite. therefore the slope of our new line will be 1/4
Now to find the y intercept follow these steps:
y=mx+b
y=1/4x+b
3=1/4(4)+b
3=1+b
b=2
Now that we have the y intercept (b) and the slope (m) we can make our equation.
y=1/4x+2
