Answer:
the first is 6 and the second is -22
Step-by-step explanation:
To find slope you need to use the slope formula which is (y2-y1)/(x2-x1)
(20-2)/(7-4)
18/3
6
slope is 6
apply that to y=mx+b
y=6x+b
apply one of the given points (I'll use (4, 2) for this )
2=6(4) +b
2=24+b
subtract 24 from each side
-22=b
y=6x-22
