Find x-intercept and y-intercept then you can draw the graph.
For example, the first question.
![y=-3x+2](https://tex.z-dn.net/?f=y%3D-3x%2B2)
To find the y-intercept, x = 0
So substitute x = 0 in the equation.
![y=0+2\\y=2](https://tex.z-dn.net/?f=y%3D0%2B2%5C%5Cy%3D2)
[Note]: You don't need to find the y-intercept, because from,
a is slope and b is y-intercept, you know b then you know y-intercept. For example b = 2 then y-intercept is at 2.
To find the x-intercept, y = 0
![-3x+2=0\\-3x=-2\\x=\frac{2}{3}](https://tex.z-dn.net/?f=-3x%2B2%3D0%5C%5C-3x%3D-2%5C%5Cx%3D%5Cfrac%7B2%7D%7B3%7D)
Therefore, y-intercept = 2 and x-intercept = 2/3
(Try do another problems, just do the same. When you want to find the y-intercept, just look at the value of b or substitute x = 0 and When you want to find the x-intercept, just substitute y = 0 then solve for x.)
(4 + 9 + 16 / 4) - 8 - (3 * 5)
(29 / 4) - 8 - (3 * 5) | Add up the numbers on left side.
(7.25) - 8 - (15) | Divide 29 by 4 and multiply 3 and 5.
-0.75 - (15) | Subtract 8 from 7.25
Final answer: -15.75

Answer:
![\boxed{ \bold{ \huge{ \boxed{ \sf{4 + 12g}}}}}](https://tex.z-dn.net/?f=%20%5Cboxed%7B%20%5Cbold%7B%20%5Chuge%7B%20%5Cboxed%7B%20%5Csf%7B4%20%2B%2012g%7D%7D%7D%7D%7D)
Step-by-step explanation:
![\sf{2(2 + 6g)}](https://tex.z-dn.net/?f=%20%5Csf%7B2%282%20%2B%206g%29%7D)
Distribute 2 through the parentheses
![\longrightarrow{ \sf{2 \times 2 + 2 \times 6g}}](https://tex.z-dn.net/?f=%20%5Clongrightarrow%7B%20%5Csf%7B2%20%20%5Ctimes%202%20%2B%202%20%5Ctimes%206g%7D%7D)
![\longrightarrow{ \sf{4 + 12g}}](https://tex.z-dn.net/?f=%20%5Clongrightarrow%7B%20%5Csf%7B4%20%2B%2012g%7D%7D)
Hope I helped!
Best regards! :D
