1. The problem is to find the equation of the line passing through the points given in the link (assuming points are (2,3) and (4,7) for demonstration). 2. The formula for the slope $m$ of a line passing through points $(x_1,y_1)$ and $(x_2,y_2)$ is: $$m=\frac{y_2-y_1}{x_2-x_1}$$ 3. Calculate the slope: $$m=\frac{7-3}{4-2}=\frac{4}{2}=2$$ 4. Use point-slope form of the line equation: $$y-y_1=m(x-x_1)$$ 5. Substitute $m=2$ and point $(2,3)$: $$y-3=2(x-2)$$ 6. Simplify: $$y-3=2x-4$$ $$y=2x-4+3$$ $$y=2x-1$$ 7. The equation of the line is: $$y=2x-1$$ This line passes through the points (2,3) and (4,7).
