Which statements are true about the location of 3.28 on the number line? Check all that apply. A number line from 1.2 to 4.2. 3.

Juliette [100K]

Answer:

- 3.28 should be plotted between 3.2 and 3.4

- 3.28 is closer to 3.0 than 4.0.

- 3.28 is closer to 3.2 than 3.4.

Step-by-step explanation:

3.28 is located towards the positive side of the number line being a positive value. Since the value is located between 3.2 and 3.4, therefore it can be plotted between this two points.

Also 3.28 is known to be closer to 3.0 than 4.0 because the difference between 3.28 and 3.0 is lower than the difference between 3.28 and 4.

4-3.28 = 0.72(larger value)

3.28-3.0 = 0.28 (smaller value)

The smaller the difference, the closer the value of 3.28 to the value in consideration.

Similarly, 3.28 is closer to 3.2 than 3.4, due to their differences. The difference between 3.28 and 3.2 is lower than the difference between 3.28 and 3.4 as shown:

3.28 - 3.2 = 0.08(smaller)

3.4-3.28 = 0.12(larger)

What is an equation for the linear function whose graph contains the points (9, 7) and (4, −8) ? Enter your answers in the boxes

Ahat [919]

$\bf \begin{array}{ccccccccc}
&&x_1&&y_1&&x_2&&y_2\\
% (a,b)
&&(~{{ 9}} &,&{{ 7}}~) 
% (c,d)
&&(~{{ 4}} &,&{{ -8}}~)
\end{array}
\\\\\\
% slope = m
slope = {{ m}}\implies 
\cfrac{\stackrel{rise}{{{ y_2}}-{{ y_1}}}}{\stackrel{run}{{{ x_2}}-{{ x_1}}}}\implies \cfrac{-8-7}{4-9}\implies \cfrac{-15}{-5}\implies \cfrac{3}{1}\implies 3$

$\bf \stackrel{\textit{point-slope form}}{y-{{ y_1}}={{ m}}(x-{{ x_1}})}\implies y-7=3(x-9)$
