Stretch should be correct.

It can't be reflection or rotation because that would result in a congruent figure (same side lengths). A dilation would result in a similar figure, where each of the sides is multiplied by a constant value, which is not the case here since one side remains the same and the other changes.

Point \blue{A}Astart color blue, A, end color blue is at \blue{(-4, 8)}(−4,8)start color blue, left parenthesis, minus, 4, comma

ASHA 777 [7]

Answer:

The coordinates of point B are (6,7).

Step-by-step explanation:

Given points are

Blue = A(-4,8)

Purple = M(1,7.5)

Green = B

It is given that point M is the midpoint of point A and B.

Let coordinates of points are (a,b).

Midpoint of two points is

$Midpoint=(\dfrac{x_1+x_2}{2},\dfrac{y_1+y_2}{2})$

$M=(\dfrac{-4+a}{2},\dfrac{8+b}{2})$

Coordinates of midpoint are (1,7.5).

$(1,7.5)=(\dfrac{-4+a}{2},\dfrac{8+b}{2})$

On comparing both sides we get

$1=\dfrac{-4+a}{2}\Rightarrow 2=-4+a\Rightarrow a=6$

$7.5=\dfrac{8+b}{2}\Rightarrow 15=8+b\Rightarrow b=7$

Therefore, the coordinates of point B are (6,7).

Please help me i really need help with this math

natima [27]

Answer:

y= 3/5x+ 6.2

Step-by-step explanation:

the slope is change in y over change in x.

-4-(-1) divided by 3-8 will be -3/-5 = 3/5

For the y-intercept, plug in x and y values. I will use (3,8).

8= 3/5(3)+b

8= 9/5+b

(subtract 9/5 from both sides)= 6 and 1/5 or 6.2 as a decimal.
