Characterize the slope of the line in the graph

katen-ka-za [31]

Answer:

Please check the attached graph.

Step-by-step explanation:

<em>Note: You did not add the graph; so I am taking a sample graph to clear the concept anyway. Please check the referred graph attached below.</em>

<em />

The slope on the graph basically tells us the time rate of change.

In other words, it describes the steepness of a straight line.

The slope can also be termed as:

Slope = rise / run

<em />

From the attached graph, taking twp points

(0, 3)

(-1, 0)

Finding the slope between (0, 3) and (-1, 0) using the formula

$\left(x_1,\:y_1\right)=\left(0,\:3\right),\:\left(x_2,\:y_2\right)=\left(-1,\:0\right)$

$\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}$

$m=\frac{0-3}{-1-0}$

$m=3$

Thus, the slope of the given line on the graph = m = 3

It's a question from real and complex numbers which I can't solve. so someone PLZ HeLp

Semmy [17]

Answer:

$\frac{1}{5}$

Step-by-step explanation:

Using the rules of exponents

$a^{m}$ × $a^{n}$ = $a^{(m+n)}$ , $\frac{a^{m} }{a^{n} }$ = $a^{(m-n)}$ , $(a^m)^{n}$ = $a^{mn}$

Simplifying the product of the first 2 terms

$\frac{a^{p^2+pq} }{a^{pq+q^2} }$ × $\frac{a^{q^2+qr} }{a^{qr+r^2} }$

= $a^{p^2-q^2}$ × $a^{q^2-r^2}$

= $a^{p^2-r^2}$

Simplifying the third term

5( $(a^p+r)^{p-r}$

= 5 $a^{(p+r)(p-r)}$ = 5 $a^{(p^2-r^2)}$

Performing the division, that is

$\frac{a^{(p^2-r^2)} }{5a^{(p^2-r^2)} }$ ← cancel $a^{(p^2-r^2)}$ on numerator/ denominator leaves

= $\frac{1}{5}$

what does it mean by "determine the equation of a line that passes through the given point. First find the slope" someone please

gtnhenbr [62]

Answer:

y=-3x-1

Step-by-step explanation:

The mistake that was made was in the denominator of the work. The second 2 should be the -1. This is what you should get:

$\frac{-7-2}{2-(-1)}$

$\frac{-9}{3} =-3$

Hope that clear things up.
