It travels 140 miles per 1 hour
Answer:
I think answer is 87<180 or maybe 87<12*15
Answer:
The equation of the line will be:
![y=\frac{5}{3}x-1](https://tex.z-dn.net/?f=y%3D%5Cfrac%7B5%7D%7B3%7Dx-1)
Step-by-step explanation:
Given the points
Finding the slope between (3, 4) and (12, 9)
![\left(x_1,\:y_1\right)=\left(3,\:4\right),\:\left(x_2,\:y_2\right)=\left(12,\:19\right)](https://tex.z-dn.net/?f=%5Cleft%28x_1%2C%5C%3Ay_1%5Cright%29%3D%5Cleft%283%2C%5C%3A4%5Cright%29%2C%5C%3A%5Cleft%28x_2%2C%5C%3Ay_2%5Cright%29%3D%5Cleft%2812%2C%5C%3A19%5Cright%29)
![\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}](https://tex.z-dn.net/?f=%5Cmathrm%7BSlope%7D%3D%5Cfrac%7By_2-y_1%7D%7Bx_2-x_1%7D)
![m=\frac{19-4}{12-3}](https://tex.z-dn.net/?f=m%3D%5Cfrac%7B19-4%7D%7B12-3%7D)
![m=\frac{5}{3}](https://tex.z-dn.net/?f=m%3D%5Cfrac%7B5%7D%7B3%7D)
The equation of the line can be obtained using the point-slope form of the equation of the line
![y-y_1=m\left(x-x_1\right)](https://tex.z-dn.net/?f=y-y_1%3Dm%5Cleft%28x-x_1%5Cright%29)
substituting the values m = 5/9 and the point (3, 4)
![y-4=\frac{5}{3}\left(x-3\right)](https://tex.z-dn.net/?f=y-4%3D%5Cfrac%7B5%7D%7B3%7D%5Cleft%28x-3%5Cright%29)
![y-4+4=\frac{5}{3}\left(x-3\right)+4](https://tex.z-dn.net/?f=y-4%2B4%3D%5Cfrac%7B5%7D%7B3%7D%5Cleft%28x-3%5Cright%29%2B4)
![y=\frac{5}{3}x-1](https://tex.z-dn.net/?f=y%3D%5Cfrac%7B5%7D%7B3%7Dx-1)
Therefore, the equation of the line will be:
![y=\frac{5}{3}x-1](https://tex.z-dn.net/?f=y%3D%5Cfrac%7B5%7D%7B3%7Dx-1)
