Question

Write the equation of the line in slope intercept form (3,3) (0,0)

Answer 1

`\begin{gathered} \text{ The equation of a line is} \\ y=mx+b \\ \\ m=\frac{y_2-y_1_{}_{}}{x_2-x_1} \\ m=(3-0)/(3-0) \\ \\ m=(3)/(3) \\ m=1 \\ \\ \text{Then y=x+b} \\ \\ \text{but } \\ 0=0+b \\ 0=b \\ \text{Thus the equation is} \\ \\ y=x \end{gathered}`
