Question

use the slope formula to determine the slope of the line containing the two points.
(-1,7) and (-5,-3)

Answer 1

\(\sf \LARGE \color{maroon}{slope \ = \ \frac{ y _{2} \ - \ y _{1} }{ x _{2} \ - x _{1} }}\)

Answer 2

do you want the proof?

Answer 3

yes

Answer 4

in mathematics - or in physics - slope is \(\sf \Large \tan \theta \)

Answer 5

ok?

Answer 6

but you need to know that in physics , \(\sf \Large \tan \theta \) is called \(\sf \large \color{green}{The \hspace{5pt} Acceleration} \)

Answer 7

and do you want to know how \(\sf \large \tan \theta \) becomes (y2 - y1)/(x2-x1) ?
