Answer:
![y=-\frac{5}{3}x-2](https://tex.z-dn.net/?f=y%3D-%5Cfrac%7B5%7D%7B3%7Dx-2)
Step-by-step explanation:
line equation in general y = mx + b
m is the slope, and
b is the y-intercept
3=-3m+b
-7=3m+b
if we plus this two equations
3-7=2b
2b=-4
b=-2
3m=b-3=-5
m=-5/3
So,
![y=-\frac{5}{3}x-2](https://tex.z-dn.net/?f=y%3D-%5Cfrac%7B5%7D%7B3%7Dx-2)
Answer:
k=3
Step-by-step explanation:
2(4k+3)−13=2(18−k)−13
2(4k+3)−13=2(18−k)−13
(2)(4k)+(2)(3)+−13=(2)(18)+(2)(−k)+−13
8k+6+−13=36+−2k+−13
(8k)+(6+−13)=(−2k)+(36+−13)
8k+−7=−2k+23
8k−7=−2k+23
8k−7+2k=−2k+23+2k
10k−7=23
10k−7+7=23+7
10k=30
10k/10=30/10
k=3
Answer:
Use the Pythagorean Theorem to find the diagonal:
![5^{2} +l^{2} =(\sqrt{125})^{2}\\ 5^{2} +l^{2} =125](https://tex.z-dn.net/?f=5%5E%7B2%7D%20%2Bl%5E%7B2%7D%20%3D%28%5Csqrt%7B125%7D%29%5E%7B2%7D%5C%5C%205%5E%7B2%7D%20%2Bl%5E%7B2%7D%20%3D125)
