Answer:

slope of the given straight line in graph is -2

Step-by-step explanation:

<u>Explanation:</u>-

in given graph we have to choose points are A(0,3) on y-axis and B(1.5 , 0) on x- axis

let m be the slope of a line

by using slope formula is

m= \frac{y_{2}-y_{1}  }{x_{2}-x_{1}  }

m = \frac{0-3}{1.5-0}

m= -2

<u>another points we have choose</u>

in given graph we have to choose points are A(0,3) on y-axis and B(2.5 , -2)

<u>slope of a line</u> :-

let m be the slope of a line

by using slope formula is

m= \frac{y_{2}-y_{1}  }{x_{2}-x_{1}  }

m = \frac{-2-3}{2.5-0}

m= -2

where ever you will take point the slope of given straight line is

m = -2

helena needs 3.5 cups of flour per loaf of bread and 2.5 cups of flour per batch of muffins. she also needs 0.75 cup of sugar pe
tatuchka [14]

The <em><u>correct answer</u></em> is:

She can make 2 loaves of bread and 4 batches of muffins.

Explanation:

Let b represent bread and m represent muffins.

The equation for the amount of flour she needs is 3.5b+2.5m=17.

The equation for the amount of sugar she needs is 0.75b+0.75m=4.5.

To solve this, we will want to eliminate one of the variables. To do this, we will make the coefficients of one of the variables the same. If we multiply 2.5 by 0.3, we get 0.75; this is what we will do to the first equation:

\left \{ {{0.3(3.5b+2.5m=17)} \atop {0.75b+0.75m=4.5}} \right.  \\ \\\left \{ {{1.05b+0.75m=17} \atop {-(0.75b+0.75m=4.5)}} \right.  \\ \\0.3b=0.6 \\ \\\frac{0.3b}{0.3}=\frac{0.6}{0.3} \\ \\b=2

She can bake two loaves of bread.

Substituting 2 for b in the first equation, we have

3.5(2)+2.5m=17

7+2.5m=17

Subtract 7 from each side:

7+2.5m-7=17-7

2.5m=10

Divide both sides by 2.5:

2.5m/2.5 = 10/2.5

m = 4

She can bake 4 batches of muffins.
