Algebra 1

Part 1: $m = \frac{25-10}{77-50}$ $m = \frac{15}{27}$ $m= \frac{5}{9}$ $y-y_{1} = m*(x-x_{1})$ $y-10 = 5/9* (x-50)$ $y-10 = 5/9* (x-50)$ $y-10 = 5/9* (59-50)$ $y-10 = 5/9* 9$ $y-10 = 5$ $y-10 + 10 = 5 + 10$ $y = 15$ Part 2:Point-slope form can be used to write the equation. Using point-slope form, a slope can be calculated and immediately inserted into the equation. Part 3:The two given points can be used ((50, 10) and (77,25)) to determine the slope.
