Answer:
D.
Step-by-step explanation:
my quiz said so
45 degrees
Since the two angles are the same
The domain is all possible values of 'x' that would make the function true. As you can see from the graph, this function goes out to infinity both ways, so all values of 'x' will satisfy the function, so your answer should be:
It would be 8.66
Hope this helped!
Answer: y = 21x + -105 or y = 21x - 105
Step-by-step explanation:
Our equation is going to be in the format of y = mx+b, where m is the slope, and b is the y-intercept.
For this, you can find the slope by doing
(y₁-y₂)÷(x₁-x₂)
So we just sub in one of the x intercept points and the point that we already have, so let's do (-21-0)/(4-5). That is equal to 21, therefore, 21 is our slope.
So we have y = 21x + b, so now we can sub in one of our points for y and x in the equation. Let's do (4,-21).
-21 = 21(4) + b
-21 = 84 + b
-105 = b
So our equation is y = 21x + -105, meaning we have a slope of 21 and a y intercept of -105.
Edit: you can also do y = 21x - 105
