Find the coordinates of the midpoint of the segment whose endpoints are h(6,4) and k(2,8)
ozzi

Answer:

(4,6)

Step-by-step explanation:

we know that

The formula to calculate the coordinates of the midpoint between two points is equal to

M(\frac{x1+x2}{2},\frac{y1+y2}{2})

we have that

The coordinates of hk

h(6,4), k(2,8)

substitute in the formula to calculate the midpoint

M(\frac{6+2}{2},\frac{4+8}{2})

M(\frac{8}{2},\frac{12}{2})

M(4,6)

Find the slope-intercept form from the two points (0,8)<br> and (1, 10).
ratelena [41]

Answer:

y = 2x + 8

Step-by-step explanation:

We want an equation of the form y = mx + b (slope-intercept).

Look what happens to x as we go from (0, 8) to (1, 10):  x increases by 1.  This is the 'run' as we calculate the slope.

At the same time, y increases by 2 from 8 to 10.

The slope is defined as m = rise / run, and here is m = 2/1, or m = 2.

Write out y = mx + b and substitute 2 for m:  y = 2x + b.

To find the y-intercept, substitute 0 (from (0, 8) ) for x and 8 for y:

8 = 2(0) = b, so b = 8, and the desired equation is

y = 2x + 8

Which of the following expressions represents a function?
PSYCHO15rus [73]
A function can have one x-value for each y-value Or even, two difference x-values for one y-value.

And out of the four options, only A and C represent a function. The other two options have the same x value for two y-values.

One way to test if it is a function is by the vertical line test.
