Answer:
We can't solve this because we can't add graphs. One way you could solve it would using Desmos.
Step-by-step explanation:
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.)
Answer:
The answer is C (0,4)
Step-by-step explanation:
Looking at the graph we have to find a point (x,y) of D.
Find point D. It is on the y-axis, but which one? Positive/Negative y-axis.
It appears to be on the positive y-axis.
Now we have to choose either option C or D.
Option C seems like the best choice since the point is (x,y) is (0,4) on the positive y-axis.
Option D is quite the opposite of point D since the point (0, -4) is on the negative y-axis.
The answer is C. (0,4)
Mr Welch bought 8 yard of fencing
Step-by-step explanation:
Mr Welch bought 24 ft of fencing
We need to find how many yards of fencing did he buy
We need to convert 24ft into yards
We are given 1 yd = 3ft
We can write
3 ft = 1 yd
then 1 ft will be:
1 ft = 1/3 yd
Now, 24 ft will be:
24 ft = 1/3*24
24 ft = 8 yard
So, Mr Welch bought 8 yard of fencing

Let the number = x
You have 15 times the number so that is 15x
9 less would be subtracting 9:
15x -9
Is 6 means the equation equals 6:
The equation is: 15x-9 = 6
