Answer:
-6
Step-by-step explanation:
y=-1/3(12)-2
=(-1/3x12/1)-2
=-4-2
y=-6
Answer:
5/7
Step-by-step explanation:
The volume formula is length x width x height. 7x5x12=420 cubic inches
Answer: Choice A
y + 1 = -3(x+2)
=============================
Explanation:
Let's look through the answer choices.
Choices C and D show that the point (2,1) is on the line. But the graph does not show this. So we can rule out choices C and D.
With choice A, the slope is negative and choice B has a positive slope.
The answer must be choice A because the line is going downhill as we move from left to right.
--------------
A common method is to pick two points on the line and compute the slope using the slope formula
m = (y2-y1)/(x2-x1)
Once you know the slope, you would use point slope form
y - y1 = m(x - x1)
