Slope = (5+7)/(1-4) = 12/-3 = -4
slope = -4
y = mx + b
-7 = -4(4) + b
-7 = -16 + b
b = 9
equation
y = -4x + 9
Answer:
When something is linear it will meet the criteria, on a graph it will be a straight line, it won't have any curves in it.
When something is nonlinear it doesn't fit the criteria, on a graph it will be curved, never straight
Hope this helps ;)
Step-by-step explanation:
I think it 1/4 i could be wrong
The top-left graph goes with the bottom-right equation, y=90(1/4)^x
The bottom-left graph goes with the top-right equation, y = 120(3/4)^x
The top-right graph goes with the bottom-left equation, y = 120(1/4)^x
The bottom-right graph goes with the top-left equation, y = 90(3/4)^x
y=90(1/4)^x has a larger percent decrease than y = 90(3/4)^x
cause if you multiply a number by 1/4, that's smaller than multiplying number by 3/4. so y=90(1/4)^x decreases really fast
same with the y = 120(3/4)^x ones
3w + 2 ( 2 - 3w ) + 2
3w + 4 - 6w +2
3w - 6w + 4 + 2
-3w + 6
