Answer:

The equation of the line is y=3x-2

Explanation:

Slope (m ) = y2-y1/ x2-x1

= 4-7/2-3

= -3/-1

m = 3

We have the slope of the line m= 3, so the line equation is

y= mx+b

y =3x+b

For instance, the first point(3,7):

y= mx +b

7=3*3+b,

7= -9 +b

b= -2

The equation of the line is y=3x-2
