WebThe slope of the line 2 x − 3 y = 9 is 2 3, which you can find by solving your equation for y (y=mx+b), and taking the x coefficient as the slope. Perpendicular lines have slopes whose product is -1, so all lines perpendicular to 2 x − 3 y = 9 will have slope − 3 2. WebFeb 18, 2024 · We are given the line equation: $ 2x + 3y = 9 $ In order to find the slope of the line we will have to convert this equation into slope-intercept form i.e., $ y = mx + c $ Therefore, we will subtract $ 2x $ from both the sides of the equation: $ 2x + 3y - 2x = 9 - 2x $ On simplifying, it will become: $ 3y = 9 - 2x $
