Question

Find the slope of the table 8 -516 -1024 -1532 -20

Answer 1

to find the slope, use the slope formula:

$m\text{ = }\frac{y2\text{ - y1}}{x2\text{ -x1}}$

Take any 2 points from the table,

(x1, y1) ==> (8, -5)

(x2, y2) ==> (16 -10)

Therefore, we have:

$m\text{ = }\frac{-10-(-5)}{16-8}=\frac{-10+5}{8}=\text{ }\frac{-5}{8}$

Therefore the slope of the table is:

$-\frac{5}{8}$
