The points (0.9),(5, 4).(2, 1) and (-3, 6) are vertices of a rectangle. Determine the coordinates of the midpoints for each side and determine if the midpoints are the vertices of a rectangle What is the midpoint of the segment with endpoints (0.9) and (5.4)?
(Type an ordered pair. Type an integer or a decimal.)

36 is the final answer! : )

step-by-step explanation:

let

we know that

the y-intercept is the y-coordinate of the point when the value of x is equal to zero

so

the y-coordinate of the point a is the y-intercept

the answer part a) is

the value of y-intercept is

part b) find the slope m

we know that

the value of the slope is equal to

substitute the values

therefore

the answer part b) is

the value of the slope is equal to

the general answer is

the slope is

the value of y-intercept is

35x 3= 105

step-by-step explanation:

35+35= 70   70 + 35= 105

c.

step-by-step explanation:

substitution for (0,1)

y=x^2+4x+1

1=0^2+4(x)0+1

1=0+4(x)0+1

1=4(x)0+1

1=0+1

1=1

substitution for (-3,-2)

y=x+1

-2=-3+1

-2=-2
