Answer:
y = -4x + 1
Explanation:
y = -4x -2 using points (4, -15)
Using y = Mx + B formula sub the x,y points in it
-15 =-4(4) + B
-15 = -16 + B then add 16 to both sides to get B alone
-15 +16 = -16+16 + B
1 = B therefore plug B back into original problem without the x,y points therefore y = -4x + 1
