Question

What is the slope of a line passing trough (-2/3) and (-4,5) ??

Answer 1

i mean (-2/5,3 ) and (-4,5)

Answer 2

remember that: (m being slope)
\[m=\frac{\Delta y}{\Delta x} \implies \frac{y_2-y_1}{x_2-x_1}\]
you are given Cartesian pairs in (x,y) form.
simply plug them in (divide change in y over change in x)
