passes through A(-3, 0) and B(-6, 5). What is the equation of the line that passes through the origin and is parallel to ?
goblinko [34]

Answer:

       Equation of line , 5x + 3y = 0

Step-by-step explanation:

The slope of a line passing through points (x₁,y₁) and (x₂,y₂) is given by \frac{y_2-y_1}{x_2-x_1}

Here points are given by (-3,0) and (-6,5)

Slope=\frac{5-0}{(-6)-(-3)}=\frac{-5}{3}

The slope of parallel lines are same. So slope of required line =\frac{-5}{3}

Equation of a line with slope m passing through origin is given by

                    y =mx

               So equation of line, y=\frac{-5}{3}x\\\\3y=-5x\\\\5x+3y=0

Equation of line , 5x + 3y = 0
