Which of the following equations will not contain point (4, 12). explain

a. y= 3/4x + 9
b. y= -1/2x + 14
c. y= 1/2x +8
d. y= -2x + 20

for brainlest answer : )

Option C.

Step-by-step explanation:

To solve this problem you must apply the proccedure shown below:

1. You have the point (4,12), therefore, to know which equation will not contain that point, you must substitute x=4 into each equation and if it contains the given point, you will obtain y=12.

2. Therefore, you have:

3. When you substitute x=4 into the equation of the option C, you obtain that y=10, therefore, that equation will not contain the point (4, 12).

-3

step-by-step explanation:

a drawing really does here:

so i draw the horizontal line y=2 and the vertical line x=-2 at this intersection i put b (this is where my right angle is going to be).   so point b is at (-2,2).   point a is 5 units long and is also on y=2 so this point has to be (3,2) or (-7,2) -doesn't matter i will go with (3,2).

now we know c is at (-2,y) we don't know the y yet bet we know that c is on x=-2.

we have the area of the triangle is .5bh=12.5

we know the base length is 5 (ab)

we have the height is (2-y) if you look at your

plug in

.5(5)(2-y)=12.5

solve for y to get the y-coordinate for c

2.5(2-y)=12.5

divide both sides by 2.5 giving:

2-y=5

now subtract 2 on both sides

-y=3

y=-3
