Question

Y = 7x + 8 y = x + 1

Answer 1

Answer:

Point of Interception: (-7/6, -1/6)

Step-by-step explanation:

y = 7x + 8

y = x + 1

Set equations equal to each other:

7x + 8 = x + 1

Subtract x on both sides:

7x + 8 = x + 1

-x           -x

6x + 8 = 1

Subtract 8 on both sides:

6x + 8 = 1

     -8    -8

6x = -7

Divide by 6:

6x = -7

/6     /6

x = -7/6

Substitute:

y = x + 1

y = -7/6 + 1

y = -1/6

Coordinate: (-7/6,-1/6)
