Answer:

perpendicular

Step-by-step explanation:

Rewrite the equations

y = (-1/7)x - 3/7 -- L1

y = 7x + 25 -- L2

Slope of L1 x Slope of L2 = -1/7 x 7 = -1

As a result, the two lines are perpendicular

Can someone give the answer
KonstantinChe [14]

Answer:

(2, -2)

Step-by-step explanation:

Given the equation

x - y = 4 ... 1

6x+y = 10 ...2

Add both expressions

x+6x = 4 + 10

7x = 14

x = 14/7

x = 2

Substitute x = 2 into equation 1;

From 1;

x - y = 4

2 - y = 4

y = 2-4

y = -2

Hence the solution to the system of equation is (2, -2)
