Answer:
The first one
Step-by-step explanation:
Because it already give you the y-intercept and you can solve x by doing 4 to 7 have to add 3 and x only have to add 1. It will give you a slope 3/1, so it is 3.
y=3x+1
Move 12 to the other side, making it negative
h=31-12
h=19
16+2x
You can’t simplify anymore since there’s no other variable or whole number.
