    Find the slope using the formula [ y2-y1/x2-x1 ].

    -9-(-12)/-15-(-24)

    3/9

    1/3

    Find the y-intercept using the formula [ y = mx + b ].

    y = 1/3x + b

    -12 = 1/3(-24) + b

    -12 = -8 + b

    -4 = b

    Use (18, 2) to see if the line passes through it

    y = 1/3x – 4

    2 = 1/3(18) – 4

    2 = 6 – 4

    2 = 2 TRUE

    Thus, the line does pass through (18, 2).

    Best of Luck!

    the line does not pass trough the point (18, 2) that other line decreases and for it to passes through the point it would have to increases
