First you normalize 3x+4y=12 into y = -3/4 x + 3 (dividing by 4).
Then you observe that the slope of the line is -3/4 (it's always the factor with the x). A perpendicular line has the reciprocal slope. Reciprocal means inverted and negated. So -3/4 becomes +4/3.
The equation will thus look like y = 4/3 x + b. To find b, we fill in the given x intercept (0,2), (we get 2 = 4/3 * 0 + b). With x=0, b must be 2.
So the equation is: y = 4/3 x + 2
I'm not 100% sure, but I'm pretty sure it's 1/12, 1/12, 1/12, 1/12
A function is a set of ordered pairs in which no two different ordered pairs have the same x -coordinate.
Btw you need to add an image so we can see which the order pairs
The length is 7 and there is no N
