the slope would be 3 I just don't know how to find the rest
where x1,y1=(2,-2) and x2,y2=(5,7)
this is the slope formula and m represents the slope
now plug int the numbers into that formula

Coordinates, not numbers. Sorry
y-7=3(x-5)?
(2,-2) (5,7) x1,y1 x2,y2 y2-y1/x2,x1 7-(-2) /5-2 =9 =3 so9/3 =3 is the answer.
that's how u do it.
so this is the answer y-7=3(x-5)
