Step-by-step explanation:
<u>Equation of a Line</u>
Two variables x and y are linearly dependent when they are related by the equation
where m is the slope and b is the y-intercept, or the value of y when x equals 0. We are given a particular equation for the line such as b=0, so we only need one point to compute m. That point is (-1,-2):
It follows that
Thus the equation of the line is
Answer:
Step-by-step explanation:
We must write the function of the line in the form 
First calculate the slope m
Then
To have b replaced a point in the function
Finally the function is
Answer:
19/5
Step-by-step explanation:
Aquí, queremos escribir el número total de millas que Hans corrió en forma de una fracción impropia.
Para hacer esto, agregamos todas las millas recorridas.
Matemáticamente, eso sería 3 + 4/5 = 3 4/5 Esta es la forma de fracción mixta.
La fracción impropia es así (5 * 3) + 4/5 = 19/5
so.. let's us eliminate, say "z" first, so for that, let's pick the 1s and 2nd equations there
so, that's our first two-variables resultant
let's pick other two, and again, eliminate the same "z" variable, this time, let's use the 2nd and 3rd equations
now, we have two two-variables equations, let's use them then
and say, we'll eliminate the "y" variable from them
