When s= -3 look at picture

when s = -3, the expression is equal to 10.

we substitute s in the equation

(-3+-7)/-1

-3+-7 is -3-7

which is...-10

-10/-1 = 10! why? negative divided by negative is a positive!

Step-by-step explanation:

-10

Step-by-step explanation:

−3−7/1

−10  

y=3x+4

step-by-step explanation:

given the points a(0,4) and b(-4, -8)

eqn of line ab: (y-4)/(x-0)=(-8-4)/(-4-0)

(y-4)/x=-12/-4=3

y=3x+4
