Write the equation to represent a line that contains the point (1, -7) and a slope of -4.
1 answer:
Answer:
y = -4x - 3
Step-by-step explanation:
It is given outright that slope is -4, so right now we have:
y = -4x
Now, plug that point's values into the current formula.
-7 = -4(1) + b
-7 = -4 + b
Add 4 to both sides to get b by itself.
-3 = b
Put -3 at the end.
y = -4x - 3
