# How to write equations for graphs

CALM Computer Assisted Learning Method This gives us the linear function $$y=-\fracx 1$$ In many cases the value of b is not as easily read. From these two points we calculated the slope $$m=-\frac$$ This gives us the equation $$y=-\fracx b$$ From this we can solve the equation for b $$b=y \fracx$$ And if we put in the values from our first point (-3, 3) we get $$b=3 \frac\cdot \left ( -3 \rht )=3 \left ( -2 \rht )=1$$ If we put in this value for b in the equation we get $$y=-\fracx 1$$ which is the same equation as we got when we read the y-intercept from the graph.
