Answer:
![\large\boxed{\text{Table 1:}\ y=4x+1}\\\boxed{\text{Table 2:}\ y=\dfrac{1}{2}x-1}](https://tex.z-dn.net/?f=%5Clarge%5Cboxed%7B%5Ctext%7BTable%201%3A%7D%5C%20y%3D4x%2B1%7D%5C%5C%5Cboxed%7B%5Ctext%7BTable%202%3A%7D%5C%20y%3D%5Cdfrac%7B1%7D%7B2%7Dx-1%7D)
Step-by-step explanation:
Tables show linear functions.
The slope-intercept form of an equation of a line:
![y=mx+b](https://tex.z-dn.net/?f=y%3Dmx%2Bb)
<em>m</em> - slope
<em>b</em> - y-intercept → (0, b)
The formula of a slope:
![m=\dfrac{y_2-y_1}{x_2-x_1}](https://tex.z-dn.net/?f=m%3D%5Cdfrac%7By_2-y_1%7D%7Bx_2-x_1%7D)
===================================================
Table 1:
(0, 1) → b = 1, (1, 5)
![m=\dfrac{5-1}{1-0}=\dfrac{4}{1}=4\\\\y=4x+1](https://tex.z-dn.net/?f=m%3D%5Cdfrac%7B5-1%7D%7B1-0%7D%3D%5Cdfrac%7B4%7D%7B1%7D%3D4%5C%5C%5C%5Cy%3D4x%2B1)
Table 2:
(4, 1), (6, 2)
![m=\dfrac{2-1}{6-4}=\dfrac{1}{2}\\\\y=\dfrac{1}{2}x+b](https://tex.z-dn.net/?f=m%3D%5Cdfrac%7B2-1%7D%7B6-4%7D%3D%5Cdfrac%7B1%7D%7B2%7D%5C%5C%5C%5Cy%3D%5Cdfrac%7B1%7D%7B2%7Dx%2Bb)
Put the coordinateso f the point (4, 1) to the equation of a line:
![1=\dfrac{1}{2}(4)+b](https://tex.z-dn.net/?f=1%3D%5Cdfrac%7B1%7D%7B2%7D%284%29%2Bb)
<em>subtract 2 from both sides</em>
![-1=b\to b=-1](https://tex.z-dn.net/?f=-1%3Db%5Cto%20b%3D-1)
![y=\dfrac{1}{2}x-1](https://tex.z-dn.net/?f=y%3D%5Cdfrac%7B1%7D%7B2%7Dx-1)
D if I'm not mistaken. Usually in these problems, they ask which is stretched, not compressed
-7a -19c
12a -30c
21a +11c
26a -38c
Answer:
should be 94°
Step-by-step explanation:
E and A =42° subtract that by 180 and you get 136° B and D also =42° so subtract again and you get 94°
Hope this helps
