Answer:
y = -2x + 39
Step-by-step explanation:
2 - 4 = -2 (with negative numbers graphs help a lot more)
0 - -1 (since there are two negatives together you change both of the signs to their opposite so they both become positive)
0 + 1 = 1
-2/1 = -2 because a negative divided by a positive is a negative
I found the y-intercept by substituting one of the points into y=mx+b
