Question

Ind the point at which the line f ( x ) = − 4 x − 1 intersects the line g ( x ) = − 2 x + 1

Answer 1

(-1,3)

Explanation:

Where the two lines intersect, they have equal values

-4x-1 = -2x + 1

-2 = 2x

x = -1

Now, you have 'x' ....use this value in either of the equations to find 'y'

-2 (-1) + 1 = y = 3

(-1,3)
