Slope = (4-0)/(0-1) = -4
b = 4

equation
y = -4x + 4

4 0

(1,0),(0,4)
slope = (4 - 0) / (0 - 1) = -4/1 = -4
the y int is when x = 0.....so ur point (0,4) tells us that the y int is 4

in y = mx + b form, the slope will be in the m position and the y int will be in the b position

y = mx + b
slope(m) = -4
y int (b) = 4
sub
y = -4x + 4 <== or 4x + y = 4....depending on what form u need it in

Answer:

Scale factor = 7

Step-by-step explanation:

Dilation with scale factor to map HEFG to DABC will be,

Scale factor = $\frac{\text{Dimension of Image DABC}}{\text{Dimension of preimage HEFG}}$

= $\frac{\text{Length of CD}}{\text{Length of GH}}$

Length of CD = Distance between two points C(0, -7) and D(-7, 0)

= $\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

= $\sqrt{(-7-0)^2+(0+7)^2}$

= $\sqrt{98}$

= $7\sqrt{2}$

Length of GH = Distance between G(0, -1) and H(-1, 0)

= $\sqrt{(-1-0)^2+(0+1)^2}$

= $\sqrt{2}$

Scale factor = $\frac{7\sqrt{2} }{\sqrt{2} }$

= 7

Write a proportion that could be used to solve for each variable. Then solve. 12 balls in 2 boxes 78 balls in x boxes

stira [4]

If 12 balls fit in 2 boxes, 6 balls fit in 1 box. 78 / 6 = 13. 78 balls fit in 13 boxes. x = 13.

Please help with math question!!

The answer to this problem is C.
Here's why:
The area of a triangle = 1/2 * (base) * (height) (Note: a triangle is half of a rectangle, and rectangles have Area = (base) * (height))

<span>Because the base of ΔAED is half of ΔACB (2 = (1/2) * 4), and height of ΔAED is half of ΔACB (3 = (1/2) * 6), we know that the area of ΔAED will be half of ΔAED.
</span>
So, it's C. I am sure =)
If it helped you, please mark me brainliest! =D
Have a nice day!
