Determine the slope and y-intercept from the following equation: 4x + y = -10
Question 9 options:
slope: 4 y-intercept: (0,10)
slope: -4 y-intercept: (0,10)
slope: -4 y-intercept: (0,-10)
slope: 4 y-interce
The first option is correct. See an explanation below.
I think I'm not sure but I think it's B
Answer:
24.3 units (3 s.f.)
Step-by-step explanation:
Since a square has 4 equal sides,
perimeter of ABCD= 4(length of AB)
Distance between 2 points
=![\sqrt{(y1 - y2)^{2} + (x1 - x2)^{2} }](https://tex.z-dn.net/?f=%20%5Csqrt%7B%28y1%20-%20y2%29%5E%7B2%7D%20%2B%20%28x1%20-%20x2%29%5E%7B2%7D%20%20%7D%20)
Length of AB
![= \sqrt{( { - 2 - 4)}^{2} + {(2 - 3)}^{2} } \\ = \sqrt{( - 6)^{2} + ( - 1)^{2} } \\ = \sqrt{37}](https://tex.z-dn.net/?f=%20%3D%20%20%5Csqrt%7B%28%20%7B%20-%202%20-%204%29%7D%5E%7B2%7D%20%20%2B%20%20%7B%282%20-%203%29%7D%5E%7B2%7D%20%7D%20%20%5C%5C%20%20%3D%20%20%5Csqrt%7B%28%20-%206%29%5E%7B2%7D%20%20%2B%20%28%20%20-%201%29%5E%7B2%7D%20%7D%20%20%5C%5C%20%20%3D%20%20%5Csqrt%7B37%7D%20)

I would say C: "I don't like it when you do that." because this clearly conveys the teacher's dislike with the student's behavior without berating them. A: "Stop being bad!" may have the opposite effect on a child and they may continue doing it just to irk the teacher further. B: "Now look what you've done!" may give the child a sense of accomplishment at making the teacher angry. <span>D: "Sometimes you're terrible." berates the child and insults them rudely. They may continue doing bad things just to infuriate the teacher as a result of that mean comment.</span>
