Answer:
m = -1, b = 5.
Step-by-step explanation:
We can find the slope, <em>m</em>, by plugging in our coordinates into the slope formula: 
. That gives us the slope. Now we can fill that in the slope intercept formula: 
. We know one of the coordinates and the slope, which allows to find the y-intercept. We know that for every 1 unit down on the line, we move 1 unit right, and vice versa. Meaning we can just count down (or up in this case), so, (-2, 7), (-1, 6), (0, 5). Therefore, our y intercept is 5.
A. 9, 12, 15
9^2 + 12^2 = 15^2
81 + 144 = 225
225 = 225
Answer: The degree of 15y+v4-8 is 1
Step-by-step explanation: Hope this helps in your studies!
0.012 as a fraction would be 12/1000, which can be simplified to 3/250. :)
