    Graphing a line...

    Graph a line with the following slope and y-intercept (note: I have a lot of difficulty with math, so please explain using easy to follow step by step instructions). Thanks!

    slope=4/7 and y-intercept (0,2)

    A simple straight line has the form of y=mx+C where m is the slope and C is a constant.

    Can you work out C for yourself by substituting in your known values?

    Slope-intercept form is y=mx+c where m is the slope and c is y-intercept.

    So in your case we have y=\frac{4}{7}x+2

    You can now plot some points from this function using a table of values, join the points to form the line.

    or simply plot one point, the y-intercept and then use the gradient to find the direction of the line.

    Do you follow?
