Answer: 3 = b (maybe, usually unsure)
Step-by-step explanation: bing
y = mx + b, this is the formula.
b = y-intercept
m = slope
1. We know that (-1,6) is our pair.
2. The formula when written with the info is y = -3x + b
3. We know that -1 is the x and the y is 6, so subbing the x and y in the formula, it is 6 = -3(-1) + b.
4. When multiplied, it becomes 6 = 3 + b
5. Then we combine like terms, by subtracting 3 into 6, making 3 = b
6. So, it is 3 = b
