Answer:

$Equation \ of \ the \ line => (y -y_{2}) =m(x -x_{2} )$

$slope, m = \frac{y_{2} -y_{1} }{x_{2} -x_{1} } =\frac{-4-2}{1--2} = \frac{-6}{3} = -2$

Equation the line passing through (-2, 2) and ( 1, -4)

$(y -- 4) = -2(x -1)\\\\(y +4) = -2x + 2\\\\y = -2x +2 -4 \\\\y = -2x -2$

option D

Answer:

If using one pound of pumpkin the baker needs to use 4 pounds of flour mixture

Step-by-step explanation:

step 1: I am going to convert the measurements

into decimals

8/5=1.6

2/5=.4

step 2: I will use cross multiplication to find out how much pumpkin for one pound of flour

1.6=.4

1=?

1*.4=.4/1.6=.25

step 3: I will convert .25 into a fraction

.25=1/4

for every 1/4 pound pumpkin, I will use 1 pound of flour

which is why

Consider the right triangle HBF. The Pythagorean theorem tells you ...
HF² = HB² + BF²

The lengths HB and BF can be determined by counting grid squares, or by subtracting coordinates. Here, it is fairly convenient to count grid squares. When we do that, we find ...
HB = 2
BF = 5
Using these values in the equation above, we get
HF² = 2² + 5²
HF² = 4 + 25 = 29
Taking the square root gives the length HF.
HF = √29
