17% you would divide 2.03 by 2.46 =.825 if you round it that would be .83. Then you subtract 83 from 100 = that equals17%. I hope I helped.

Answer:

$\boxed{\sf{4}}}$

Step-by-step explanation:

Use a slope form.

<u>Slope:</u>

$\sf{\dfrac{y_2-y_1}{x_2-x_1}=\dfrac{rise}{run} }$

y₂ = (17)

y₁ = (1)

x₂ = (2)

x₁ = (-2)

Then, rewrite the problem.

Solve.

$\sf{\dfrac{17-1}{2-(-2)}=\dfrac{16}{4}=\dfrac{16\div4}{4\div4}=\dfrac{4}{1}=\boxed{\sf{4} }$

Therefore, the slope is 4, which is our answer.

I hope this helps you! Let me know if my answer is wrong or not.

Choose the point-slope form of the equation of this line.

igor_vitrenko [27]

Answer:

y= -5x +7

Step-by-step explanation:

We can see points on the graph:

(2, -3) and (3, -8)

The function in general form is:

y= mx+b

Let's find the slope and y-intercept as per identified points on the graph:

m= (y1-y1)/(x2-x1)

m= (-8+3)/(3-2)= -5

b= y- mx

b= - 3 -(-5)*2= -3 +10= 7

Based on the found values of m and b, the given line is:

y= -5x +7

Find the distance between the points. (Round your answer to two decimal places. (9.7, - 2.8), (- 3.2, 8.8)

Dmitry [639]

Answer:

Rounding it to two decimal places, we get distance, $d=17.35$

Step-by-step explanation:

Given:

The two points are $(9.7, -2.8)\textrm{ and }(-3.2, 8.8)$

The distance between the two points can be obtained using the distance formula which is given as:

$d=\sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2}$

Here, for the points, $(9.7, -2.8)\textrm{ and }(-3.2, 8.8)$

$x_{1}=9.7,x_{2}=-3.2,y_{1}=-2.8,y_{2}=8.8$

Therefore, the distance between the points is:

$d=\sqrt{(-3.2-9.7)^2+(8.8-(-2.8))^2}\\d=\sqrt{(-12.9)^2+(8.8+2.8)^2}\\d=\sqrt{(12.9)^2+(11.6)^2}\\d=\sqrt{166.41+134.56}\\d=\sqrt{300.97}=17.348$

Rounding it to two decimal places, we get $d=17.35$
