find the gradient of the line the formula

the formula for the gradient is

$$m = \frac{(y _{2} - y _{1})}{(x _{2} -x _{1})}$$

m = (-6 -1)/(-6 +3)

$$m = \frac{-7}{-3}  =========> m = \frac{7}{3}$$

next the equation of the line in point slope form is 

y = mx + b

or 

$$y = \frac{7x}{3} + b$$

choice either point  say ( -3, 1) substitute into the equation above and find b

then you'll have the equation of the line
