can someone show me how to graph this
x+4y=8

  • algebra 1 -

    Start with drawing the x- and y-axes.
    Since this is a linear equation, the graph is a straight line, which requires a minimum of two points to plot. However, it is advisable to plot the line with three points in case there is a mistake in the calculations.
    Given: x+4y=8
    Assume a value of x, substitute the value of x in the equation and solve for y.
    For example, x=0, then 0+4y=8, which gives y=8/4=2. So (0,2) is one point on the graph.

    Proceed in a similar way to get two more points on the graph and plot them. Join the three points and they should lie on a straight line. If the line is not straight, there would be a mistake in the calculations.
