Remember,
To subtract 2/3-1/2 you have to make them equivalent
2/3×2-1/2×3 = 4/6 - 3/6=
1/6
The slope of this line is the difference of the y values divided by the difference of the x values. Solving this give 4/-3. Then, you already know the b in y = mx+b, which is 2, because you already have the value (0, 2). So, the answer is y =
x + 2
The slope of the given line is 2.
The slope of the line perpendicular to the given line is the negative reciprocal of 2 or -1/2.
Answer: -1/2
