Step-by-step explanation:
recall in a linear equation expressed in the form
y = mx + b,
m represents the slope or the rate of change in the value of y for a unit change in the value of x
b represents the y-intercept (i.e the value of y when x = 0)
If you compare these definitions to what was given in the question, the rate of change in snowfall is given as 1/2 inches per hour. This is equivalent to the m value in our general equation above. Hence we can say that the rate of change in snowfall is equal to the slope of the graph.
The question also states that before the snow even started to fall (i.e when x=0 hours), there was already 8 inches on the ground. This is equivalent to the value of b in our general equation above. Hence we can say that the y-intercept is representative of the 8 inches that was already on the ground when the snow started falling.
Answer:
In the pic
Step-by-step explanation:
The dots that I used are from counting squares on A
* m = slope
* it's doesn't matter how you label each dot, you will get the same answer in the end.
JUST MAKE SURE THAT YOU DON'T MIX UP THE COORDINATES !!!
If you have any questions about the way I solved it, don't hesitate to ask me in the comments below
The first one would have a y-intercept of (0,-6) and the second one would have a y-intercept of (0,8) <span>and x (the slope) would still be the same.
</span><span>y=x-6 would have points with (0,-6) (2,-4) (4,-2) (6,0)
y=x+8 would have points with (0,8) (-2,6) (-4,4) (-6,2)
</span><span>In other words shifted up. Hope this helps!</span>
A model shows the visualize of what you need to do in order to complete the problem your asked. It can also show important steps and make it easier for you to answer the question, like length×height×width.
Where you stop/finish. hope that helps :)
