Which is the equation of a line that is perpendicular to 8x + 6y = –5? a. y=2/3x-3/4 b. y=3/4x-3/4 c. y=4x+6 d. y=6x-4

The perpendicular line will have an equation of y=3/4x-3/4

To find this, we first have to solve our equation for slope intercept form.

8x + 6y = -5 > subtract 8x

6y = -8x + -5 > divide by 6

y = -4/3x - 5/6.

So we know the slope of this equation to be -4/3. Since perpendicular lines have opposite and reciprocal slopes, we know we can simply flip the fraction and make it a negative to get the new slope of 3/4. Since B is the only option with that slope, we know it to be the correct answer.
