Choose the general form of the equation of the line that satisfies the given condition

1.	With −10 as slope and 14 as x-intercept

10 x - y + 140 = 0

102 x + y + 14 = 0

10 x + y - 140 = 0

none of the choices

Answer: $10 x + y - 140 = 0$

2.	Passes through the origin and is parallel to the line $2 x - 7 y = 14$

7 x - 2 y = 0

2 x - 7 y = 0

7 x + 2 y = 0

none of the choices

Answer: $2 x - 7 y = 0$

3.	Passes through the origin and is perpendicular to the line $2 x - 7 y = 14$

7 x + 2 y = 0

2 x - 7 y = 0

2 x + 7 y = 0

none of the choices

Answer: $7 x + 2 y = 0$

4.	Passes through the point $(13, - 6)$ and with equal x- and y-intercepts

x - y = 7

x + y = 7

- x - y = 7

none of the choices

Answer: $x + y = 7$
