Answer:
Step-by-step explanation:
7x - 1 + 6x - 1 = 180
13x - 2 = 180
13x = 182
x = 14
7(14) - 1 = 98 - 1= 97
6(14) - 1 = 84 - 1 = 83
Answer:

Answer: -4/7
Step-by-step explanation:
To find the slope, let's change the equation to slope-intercept form.
[subtract both sides by 4x]
[divide both sides by 7]
![y=-\frac{4}{7}x+\frac{9}{7}](https://tex.z-dn.net/?f=y%3D-%5Cfrac%7B4%7D%7B7%7Dx%2B%5Cfrac%7B9%7D%7B7%7D)
Now, we know the slope is -4/7.
