Find the equation of straight line whose slope is 10 3 and passes through the point 0 , 5 .

Given: Slope m = 10 3 Co-ordinates of point x 1 , y 1 = 0 , 5 We know that, y - y 1 = m x - x 1 y - 5 = 10 3 x - 0 3 y - 15 = 10 x - 0 10 x - 3 y + 15 = 0 Hence, the equation of straight line is 10 x - 3 y + 15 = 0 .

Find the equation the straight line whose slope is 2 3 and passing through 5 , - 4 .

Given: Slope of line m = 2 3 and line passes through 5 , - 4 Slope of line m = y 2 - y 1 x 2 - x 1 Here, x 1 = 5 y 1 = - 4 x 2 = x coordinate of another point is x y 2 = y coordinate of another point is y Putting the values in the slope formula, ⇒ 2 3 = y - - 4 x - 5 ⇒ 2 x - 5 = 3 y + 4 ⇒ 2 x - 10 = 3 y + 12 ⇒ 2 x - 3 y - 22 = 0 Hence, the equation is 2 x - 3 y - 22 = 0
