Question

Slope of the line that contains (-8,2) , (7,-4)

Answer 1

-2/5

Explanation:

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

m=(-4-2)/(7-(-8))

m=-6/(7+8)

m=-6/15

simplify

m=-2/5

Answer 2

`\mathsf{slope=-\frac25}`

Explanation:

`\mathsf{let \ (x_1,y_1)=(-8,2)}`

`\mathsf{let \ (x_2,y_2)=(7,-4)}`

`\mathsf{slope=(y_2-y_1)/(x_2-x_1)}`

`\implies \mathsf{slope=(-4-2)/(7--8)=-\frac25}`
