    Answer:

    y = 7x – 9

    slope = 7

    draw on graph

    x y

    -3. -30

    -2. -23

    -1. -16

    0. -9

    1. -2

    2. 5

    3. 12

    y intercepts at x= 0 which is -9

    y = 3x -1

    slope = 3

    x y

    -3. -10

    -2. -7

    -1. -4

    0. -1

    1. 2

    2. 5

    3. 8

    y intercepts at x= 0 which is -1

    for x= 2 , y = 5 in both graphs

    so (2,5) is intersection point

    or we can solve by equating equation

    7x-9 = 3x-1

    4x = 8

    x=2

    y = 3*2 -1 = 5

    (x,y) = (2,5)
