Question

What is the slope of the line that is perpendicular to the line whose equation is  3x +2y = 9?

Answer 1

Line equation: 2y + 3x = 9
Answer: `a = 2/3`

Explanation:

Equation of the Line (1) in slope-intercept form:

`2y = - 3x + 9` -->`y = - (3x)/2 + 9/2`

Slope of Line (2) that is perpendicular to Line (1): `2/3`. The product of the 2 slopes must be (-1).
