    A. y = 3 over 2x − 3 B. y = 3 over 2x + 3 C. y = negative 2 over 3x + 23 over 3 D. y = negative 2 over 3x − 23 over 3

    is y2 -y1/x2-x1?

    no that is the formula for finding slope the formula for point slope is \[y -y _{1}=m(x-x _{1})\]

    *hint since it is parallel the slope are the same

    the slope is 2?

    is this how your equation looks \[y=\frac{ 2 }{ 3 }x+3\] is so then the slope is 2/3x

    now you plug in the values the slope for m and the point (7,3) for x(1) and y(1)

    so y - 3 = m(x-7) ?

    k idk what you did to get that lol but when you distribute you should get \[y-3=-\frac{ 2 }{ 3 }x-\frac{ 14 }{ 3 }\]

    wait it should be \[y-3=-\frac{ 2 }{ 3 }+\frac{ 14 }{ 3 }\]
