    The slope-intercept form: y = mx + b

    We have the slope m = 9, therefore: y = 9x + b.

    Next. We have the table:

    x | - 5 | - 2 | 1 | 3 | 4 |

    y |-46|-19| 8 |26|35|

    (1, 8) → x = 1, y = 8

    substitute the values of x and y to the equation:

    8 = 9 (1) + b

    8 = 9 + b |-9

    b = - 1

    Answer: y = 9x - 1 → y-intercept is - 1.
