Question

Which is the equation of the line that passes through the points (4,3) and (6,2)
A. Y = x - 1
B. Y = 0.5x - 1
C. Y = -0.5x + 5
D. Y = -0.5x + 1

Answer 1

Answer:

Y = -0.5x + 5. (option C)

Step-by-step explanation:

First, we need to find the slope of the given points.

y2-y1 divided by x2-x1

2-3/6-4 = -1/2

So, the slope of the line is -0.5

Next, we have to sub. m= -0.5 (x,y) = (6,2)

y= mx+b, need to solve fox b.

2 = -1/2(6) + b

2 = -3 + b

5 = b

So, the final answer is Y = -0.5x + 5.
