so you're going to need to find the slope. in order to do that use (y2-y1)/(x2-x1)
(7-(-2))/(0-8)
simplify
9/-8
simplify -9/8
now using y=mx+b, we need to find b. so we can plug in the coordinates of (0,7) or (8,-2). let's use (8,-2) because it involves more math.
y=mx+b
-2=(-9/8)(8)+b
multiply (-9/8) by 8 to get -9
-2=-9+b
add 9 to both sides
7=b
so our equation is now
y=-(9/8)x+7
Answer:
It would be 30.
Step-by-step explanation:
B) 2x+1 < 7 and -2x +1 < 9
C) -4 < x < 3
D) -4 <[equal to] x <[equal to] 3
42 because you take 46 and add 42 it will be 88 and the one sister is still 2 years older
