slope = m = (y2 - y1)/(x2 - x1)

(y2 - y1)/(x2 - x1) = m

(-1 - 1)/(-1 - x) = 2/7

-2/(-1 - x) = 2/7

2/(x + 1) = 2/7

1/(x + 1) = 1/7

x + 1 = 7

x = 6

The formula of a slope:

$m=\dfrac{y_2-y_1}{x_2-x_1}$

We have the points (-1, -1), (x, 1) and the slope m = 2/7. Substitute:

$\dfrac{1-(-1)}{x-(-1)}=\dfrac{2}{7}$

$\dfrac{2}{x+1}=\dfrac{2}{7}$ cross multiply

2(x+1)=(2)(7) use distributive property

2x+2=14 subtract 2 from both sides

2x=12 divide both sides by 2

x=6

x = 6

Infinitely many solutions

Step-by-step explanation:

2(3x+4)=6x+8

6x+8=6x+8

Therefore, there are infinitely many solutions because both sides will always be equal to each other since they have the same slope and y-intercept.
