Question

Which set of points would result in a slope of 1/4?

(8, 2) and (4, 1)
(8, 2) and (1, 4)
(2, 8) and (4, 1)
(2, 8) and (1, 4)

Answer 1

Hint: use the slope formula

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

Answer 2

For example, the slope through (8,2) and (1,4) is...

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

\[\Large m = \frac{4-2}{1-8}\]

\[\Large m = \frac{2}{-7}\]

\[\Large m = -\frac{2}{7}\]

So choice B isn't the answer
