I think it is C., since they are not a group of friends or people he personally knows, just 100 people out of everyone attending his school, I think that is unbiased and has a widespread enough population.

What is the equation of the line through (4,5) and (0,-3)

Allisa [31]

Answer:

y = 2x - 3

Step-by-step explanation:

Slope intercept equation of a line:

y = mx + b

(0, -3) is the y-intercept, so b = -3

We have

y = mx - 3

Now we use the two points to find the slope.

slope = m = (-3 - 5)/(0 - 4) = -8/(-4) = 2

y = 2x - 3

I need some helppp people

We can observe that the function describing the graph is linear and so the equation is of linear nature:

$y=mx+n$

Numbers m and n have special names. m is called the slope, n is called y-intercept.

From the graph one can tell that the line intercepts y-axis at y = -1 that means n = -1. What about the slope you say?

The slope can be calculated using two points' coordinates that lie on the line:

$m=\frac{\Delta y}{\Delta x}=\frac{-1-5}{0-5}=\frac{6}{5}$

Now our line has an equation,

$y=\frac{6}{5}x-1$

Hope this helps.

We have a right triangle with hypotenuse 38 and leg 34.
We want to find the other leg.

We use the Pythagorean Theorem:
$a^{2}+b^{2}=c^{2}$
$\Rightarrow a^{2}+34^{2}=38^{2}$
$\Rightarrow a^{2}+1156=1444$
$\Rightarrow a^{2}=288$
$\Rightarrow a=12\sqrt{2}\approx 17.0$
