Question

What is the slope for (-4,7), (-6,-4) and the slope for (15,8) (-16,9)​

Answer 1

#1

Slope

`\\ \tt\dashrightarrow m=(-4-7)/(-6+4)`

`\\ \tt\dashrightarrow m=(-11)/(-2)`

`\\ \tt\dashrightarrow m=(11)/(2)`

#2

Slope

`\\ \tt\dashrightarrow m=(9-8)/(-16-15)`

`\\ \tt\dashrightarrow m=(1)/(-31)`

Answer 2

see below

Explanation:

slope for (-4,7), (-6,-4)

m = (y2-y1)/(x2-x1)

= ( -4-7)/(-6- -4)

= (-4-7)/(-6+4)

= -11/-2

= 11/2

slope for (15,8) (-16,9)

m = (y2-y1)/(x2-x1)

= (9-8)/(-16-15)

= 1/ -31

= -1/31
