Question

Find the equation of a line perpendicular to 2x+4y=8 which cross the y intercept

Answer 1

Answer:
`y=2x+2`

Explanation:

`2x+4y=8\\\\x+2y=4\\\\2y=-x+4\\\\y=-(1)/(2)x+2`

So, the slope of the given line is -1/2, meaning the slope of the line we want to find is 2.

Since the y-intercept is the given line is (0,2), the equation is
`y=2x+2`
