A function is a relation where each value in the domain is associated with an unique value in the range, that is, one domain value can't be associates with two differente range values. This is why the answer is 6, that way the definition of a function will be acomplished.

Therefore, the answer is H. 6.

Find the length of line segmentAB which joins the following points.A(10, 14) and B(2,6)​
Helen [10]

Answer:

The equation of the line AB is  y - x -4 = 0

Step-by-step explanation:

The points are A (10,14) and B(2,6)

Now, slope of the line AB :  m = \frac{y_2 - y_1}{x_2 - x_1}

or, m = \frac{14 -6 }{10 - 2} = \frac{8}{8}  = 1

So, slope of the equation AB = 1

Now, by SLOPE INTERCEPT FORM:

The equation of line is given as :    y - y0 = m (x-x0)

So,the equation of line AB is  y - 6 = 1(x-2)

or, y - 6 -x + 2 = 0

or, y - x -4 = 0

Hence, the equation of the line AB is  y - x -4 = 0

Write the equation of the line that passes through the points (4,-6) and (-2,3)
yarga [219]

Here is your answer and an explanation

Answer: y = -2/3x

Explanation:

This can be determined by calculating the gradient of the straight line, using:

m=ΔyΔx

=−6−34−(−2)

=−96

=−32

Then we use the slope-point form of the straight line:

y−y1=m(x−x1)

to give:

y−3=−32(x−(−2))

∴y−3=−32(x+2)

∴y−3=−32x−3

∴y=−32x

Find the y intercept only.<br> 4x – y = 4
faltersainse [42]

Answer:

ok so first we have to convert this into y intercept

4x-y=4

-4x

-y=-4x+4

*-1

y=4x-4

so the y intercept is -4

Hope This Helps!!!
