Question

find an equation of the line that satisfies the given condition. Through (8,7) and (7,9)

Answer 1

First find the slope:
\[\LARGE m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}\]
Then use the point slope formula:
\[\LARGE y-y_{1}=m(x-x_{1})\]
Then just get it into slope-intercept form
\[\LARGE y=mx+b\]
