What is the linear function for
slope= -6 x intercept 8
slope= 2 y intercept 7
Points= (3,4), (5,9)
:
1) use point slope formula which is y-k=m(x-h) where m is the slope and (h,k) is any point on the line . our point is (8,0)
:
y-0=-6(x-8)

:
2)slope intercept form y=mx+b where m is the slope and b is the y intercept
:
highlight%28y=2x%2B7%29
:
3)find slope and then use point slope formula using either point as your one point. slope=m =(9-4)/(5-3)=4/2=2. I am using (3,4)
:
y-4=2(x-3)
:
y-4=2x-6
:
