Answer:
1
Explanation:
Y=mx+b
so find your slope
y2-y1/x2-x1 so 13-7/4-2
you get 6/2 or simplified 3
so now you have the equation y=3x+b
next you want to plug in a point to your equation so
7=3(2)+b
now solve using PEMDAS
7=6+b
then you want to isolate your variable
7 = 6 + b
-6 -6
1=b and thats your slope intercept
hope this helped :)
