In the lyrics of
We Will Graph You we can find some information regarding the line we want to draw. The words
a line is when is nil we read as when Therefore, the graph has its -intercept at We have now found one point on the graph.
The next line,
and decrease to when is , gives us another point on the line, Let's mark this point in the diagram as well.
Next Brian tells us to draw the graph. We will, we will graph it by connecting the points with a line.
Brian May next puts us under pressure to find the slope of this line. But we are champions so we go ahead and present a formula that will help us calculate the slope . The points we used when we drew the line can be helpful in finding and
We will now substitute and for and in the formula and, like a kind of magic, we find the slope.
The final line before the chorus tells us to find
its and -intercepts. We already know the -intercept, The intercept we can identify by looking at the graph.
The line intercepts the axis at Therefore, the intercept is Let's summarize what we have found about this graph.
