Step-by-step explanation:

Slope-intercept form: →
y=mx+b

m: represents the slope and is constant.

b: represents the y-intercept.

You can also to used rise/run.


(rise)/(run)


m=(rise)/(run)


Slope=(y^2-y^1)/(x^2-x^1)


(x^1, y^1)=(4,2)


(x^2, y^2)=(1, -7)


rise=y^2-y^1=-7-2=-9


run=x^2-x^1=1-4=-3

You can also divide into the -3 are:


-9/-3=3

But the slope is 3.

But the y-intercept is -3.

Hope this helps!

Thanks!
