Have a wonderful day.
The slope-intercept form:
![y=mx+b](https://tex.z-dn.net/?f=y%3Dmx%2Bb)
m - slope
b - y-intercept
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)
We have two points (2, 0) and (-2, -4). Substitute:
![m=\dfrac{-4-0}{-2-2}=\dfrac{-4}{-4}=1](https://tex.z-dn.net/?f=m%3D%5Cdfrac%7B-4-0%7D%7B-2-2%7D%3D%5Cdfrac%7B-4%7D%7B-4%7D%3D1)
Therefore we have the equation of a line
![y=1x+b\to y=x+b](https://tex.z-dn.net/?f=y%3D1x%2Bb%5Cto%20y%3Dx%2Bb)
Put the coordinates of the point (2, 0) to the equation:
<em>subtract 2 from both sides</em>
![-2=b\to b=-2](https://tex.z-dn.net/?f=-2%3Db%5Cto%20b%3D-2)
Answer: ![\boxed{y=x-2}\to\boxed{3)}](https://tex.z-dn.net/?f=%5Cboxed%7By%3Dx-2%7D%5Cto%5Cboxed%7B3%29%7D)
First we have to simplify
3r + 2 < 5
subtract 2 from each side then divide by 3
r < 1
7r - 10 > 60
add ten to both sides. divide by 7.
r > 10
answer: r<1 or r>10
if you have to graph, you should have a number line going from 0 to 11. You should put an open circle on 1 and an open circle on 10. Shade to the left from the open circle on 1, and then shade from the right from the open circle on 10.
Your union should look like this:
(-♾, 1)U(10,+♾)
