Answer:
y=-4x+8
Step-by-step explanation:
To find the equation of a line given two points, use the slope formula. In this case, the slope is -4. The equation becomes y=-4x+b. To solve for b, plug in one of the points and solve for b. In this case we'll use (1,2). This gives us 2=-4(1)+b or b=6. Therefore, our final answer is y=-4x+8
