Question

Find the value of x so that the line passing through (10, 5) and (x, 9) has a slope of -2

Answer 1

I'll get you started


\[\Large m = \frac{y_{2}-y_{1}}{x_{2}-x_{1}}\]


\[\Large -2 = \frac{9-5}{x-10}\]


\[\Large -2 = \frac{4}{x-10}\]


\[\Large -2(x-10) = 4\]


and I'll let you finish

Answer 2
