Hello there!
Answer:
The slope is 9, and the y-intercept is –2
Step-by-step explanation:
The equation is y = 9x - 2
This follows the equation y = mx + b
Where as:
m = slope
b = y-intercept
When you know this, you would figure out that 9 is in the same place as m, and -2 is in the same place as b.
The y-intercept would not be a positive 2 because when there's a minus sign next to the number in the y-intercept spot, then you would have to bring that over to the number. We can also say the minus sign belongs to the 2, making it a -2.
With the information we know now, we can say that the slope of the equation is 9, and the y-intercept would be -2.
Therefore, giving your answer as "The slope is 9, and the y-intercept is –2"

I’m right about Ron’s not so sure about teddys
Answer:
262 in
Step-by-step explanation:
the equation for volume of a sphere is : 
r
so replacing the number of the radius into the equation, it would look like:
r
which gives you 523.59878 in
but since it's a hemisphere, you'd divide it in half, which gives you 261.79939.
since you're rounding off to the nearest whole number, you're answer is 262 in
Answer:
83 degrees
Step-by-step explanation:
Supplementary angles are two angles whose sums add up to 180 degrees. Since you have one angle that is 97 degrees and one that is unknown, you can just subtract 97 from 180.
180 - 97 = 83 degrees
The correct answer is 10/9 or 1.1. Hope this helps.
