Answer:
yes plz post one
Step-by-step explanation:
Since you don't know the value of b about the best that you could do is:
(2b)^4
16b^4
16b*b*b*b
ANSWER:
![y=2x-1](https://tex.z-dn.net/?f=y%3D2x-1)
STEP-BY-STEP EXPLANATION:
We have that the equation in its slope-intercept form is the following:
![\begin{gathered} y=mx+b \\ m\text{ is the slope and b is the y-intercept } \end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%20y%3Dmx%2Bb%20%5C%5C%20m%5Ctext%7B%20is%20the%20slope%20and%20b%20is%20the%20y-intercept%20%7D%20%5Cend%7Bgathered%7D)
The slope can be calculated as follows:
![m=\frac{y_2-y_1}{x_2-x_1}](https://tex.z-dn.net/?f=m%3D%5Cfrac%7By_2-y_1%7D%7Bx_2-x_1%7D)
We use the points (4,7) and (1,1) to calculate the slope:
![m=\frac{1-7}{1-4}=\frac{-6}{-3}=2](https://tex.z-dn.net/?f=m%3D%5Cfrac%7B1-7%7D%7B1-4%7D%3D%5Cfrac%7B-6%7D%7B-3%7D%3D2)
Now, we calculate the value of b, using the point (1,1) and the slope, like this:
![\begin{gathered} 1=1\cdot2+b \\ b=-2+1 \\ b=-1 \end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%201%3D1%5Ccdot2%2Bb%20%5C%5C%20b%3D-2%2B1%20%5C%5C%20b%3D-1%20%5Cend%7Bgathered%7D)
Therefore, the equation would be:
X=3
91 + x^2
91 + 3^2
91 + 9
91 + 9 = 100
