Question

A line passes through the point (4,-2) and has a slope of 1/2

Answer 1

Answer:

y = 1/2x - 4

Step-by-step explanation:

First, write the equation using the slope: y = 1/2x + b. Next, find the y intercept by plugging in the point. It should look like this: -2 = 1/2(4) + b. Multiply 1/2 by 4 to get 2. This is what it looks like now: -2 = 2 + b. Subtract 2 from both sides to get -4 = b. Go back to your original equation and plug in -4 for b. This is your final answer:

y = 1/2x - 4
