What would you write for the rang of this graph

VladimirAG [237]

The range of any graph are the set of all the y-values of the graph. For this graph, it goes all the way from 0 to about 3.5. I'd say the range of this graph was {0, 3.5}. Hope I could help!

Find the slope of a line passing through these ordered pairs. Show your work. (2, 4) (15, 9)

Anuta_ua [19.1K]

Answer:

The slope of line passing through points (2 , 4) and (15 , 9) is $\dfrac{5}{13}$

Step-by-step explanation:

Given as :

A line is passing through the points

i.e $x_1$ , $y_1$ = 2 , 4

And $x_2$ , $y_2$ = 15 , 9

Let The slope of line = m

Now, Slope of line is determine as

slope = $\dfrac{y_2-y_1}{x_2-x_1}$

Or, m = $\dfrac{y_2-y_1}{x_2-x_1}$

Or, m = $\dfrac{9 - 4}{15 - 2}$

Or, m = $\dfrac{5}{13}$

So, The slope of line = m = $\dfrac{5}{13}$

Hence, The slope of line passing through points (2 , 4) and (15 , 9) is $\dfrac{5}{13}$ Answer
