    I would use desmos again. Graph the function and then click the x-intercepts and you should see coordinates pop up

    they want the x intercepts so the points where the graph crosses the x axis

    when you have 2x-5y=10 and 4x-10y=20 to graph them you have to get the y on one side right?

    yeah you can solve for y, but desmos allows you type in 2x-5y=10 as is same with the other equation
