let f be a function by f(x)= -5x-3, D is its graph. Determine the coordinates of the point of intersections of D with the x-axis and the y-axis


  1. Indirectly we are asked for x and y intercepts because
    • The point at which a line crosses x axis is called its x intercept and there y coordinate is 0.
    • Similarly the point at which a line crosses y axis is called its y intercept and there x coordinate is 0
    Let us find out
    • f(x)=-5x-3
    Y intercept:
    put x=0
    • y=-5(0)-3
    • y=-3
    X intercept
    put y=0
    • -5x-3=0
    • -5x=3
    • x=-3/5
