I'm having trouble with some equations. I've tried to get the equation I need for these problems, but what I know how to do does not seem to be working.
1. Find the equation of the line that passes through (1/2,-2/3) and is perpendicular to the line 4x+8y=1. Give answer in point slope form.
Are there any tips on how to find perpendicular lines?
2. Find the slope and y-intercept of the line 6y+3=0.
the slope is zero
I'm confused as to how to find the y-intercept. I had been doing this, but it's not correct.
