A line passes through the points (1,4) and (3, 4). Which is the equation of the line? O
y=-4x+8
O y=-2x + 6
0 x = -1 &x+2
O y=2x + 2

None of the above.

y = 4

Step-by-step explanation:

Step 1: Find slope

m = (4 - 4)/(3 - 1)

m = 0/2

m = 0

Step 2: Write out equation:

y = b

Step 3: Find b

4 = 1(0) + b

b = 4

Step 4: Rewrite equation

y = 4

You can also just figure out y = 4 by looking at the coordinates given. Any value of x will always be the same output of y, which equals 4. So your line would have to be y = 4, which has no slope.

-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
