The slope is already solved for you!! :-)) For each line that has the basic
y = 1/5 x, the slope is 1/5. What magic is this?!? Basically, given that the equations have no other values of x such as x square (parabola - which would have no definite slope) the slope will always be 1/5 because of this:
y = slope times x plus y-intercept :-) I hope this helps
