Answer:
A) (-4,-1)
Step-by-step explanation:
a line graphed with those coordinates would have a slope of -3/12, or -1/4.
Following that slope, you would go through (-4,-1). So that is the point collinear with the given points.
In the given graph, lets mark two points:
Let
and ![B = (4,-2)](https://tex.z-dn.net/?f=B%20%3D%20%284%2C-2%29)
The slope of the line is given by:
![m = \frac{(-2)-(-3)}{(4)-(0)}](https://tex.z-dn.net/?f=m%20%3D%20%5Cfrac%7B%28-2%29-%28-3%29%7D%7B%284%29-%280%29%7D)
![m = \frac{-2+3}{4}](https://tex.z-dn.net/?f=m%20%3D%20%5Cfrac%7B-2%2B3%7D%7B4%7D)
![m = \frac{1}{4}](https://tex.z-dn.net/?f=m%20%3D%20%5Cfrac%7B1%7D%7B4%7D)
The equation of the line is given by:
![(y-y_1)=m(x-x_1)](https://tex.z-dn.net/?f=%28y-y_1%29%3Dm%28x-x_1%29)
![(y-(-3))=(\frac{1}{4})(x-0)](https://tex.z-dn.net/?f=%28y-%28-3%29%29%3D%28%5Cfrac%7B1%7D%7B4%7D%29%28x-0%29)
![4(y+3)=x](https://tex.z-dn.net/?f=4%28y%2B3%29%3Dx)
![4y+12=x](https://tex.z-dn.net/?f=4y%2B12%3Dx)
![4y=x-12](https://tex.z-dn.net/?f=4y%3Dx-12)
![y= \frac{1}{4}x-3](https://tex.z-dn.net/?f=y%3D%20%5Cfrac%7B1%7D%7B4%7Dx-3)
Therefore, the function equation represented by the graph is: ![f(x)= \frac{1}{4}x-3](https://tex.z-dn.net/?f=f%28x%29%3D%20%5Cfrac%7B1%7D%7B4%7Dx-3)
Answer:
The answer would be 5x-18=13
Step-by-step explanation:
When given five times than a number, 5 would be multiplied by (x) since x can be any number. Less than 18 means subtract 18. Is equal to means an eual sign and the equation is equal to 13.
