Find the distance between the x-intercept and the y-intercept of the graph of the equation 2x - 5y = 10.
2x - 5y = 10
x-intercept: 2*x - 5*0 = 10 so x = 5 x-intercept at point (5, 0)
y-intercept: 2*0 - 5*y = 10 so y = -2 y-intercept at point (0, -2)
Use Pythagoras to find distance between them: r = √[(0-5)2 + (-2-0)2]
