The equation below describes a proportional relationship between x and y. What is the constant of proportionality? Y=4/7x

FromTheMoon [43]

Answer:

the given equation is y=4/7x

reciprocating both sides you get y/x =7/4

now x and y are directly porportional to each other so

x=ky where k is the constant

or x/y=k ......................(2)

equating 1 and 2

k=7/4

Complete the equation of the graphed linear function in point-slope form. y – (–2) = (x – ) The graph of the function goes throu

sammy [17]

Answer:

$y-(-2) = 4(x-1)$

Step-by-step explanation:

Point-slope form of the equation of a straight line is:

$y-y_0 = m(x-x_0)$ (1)

The two points given in the problem are:

$(x_0,y_0)=(1,-2)\\(x_1,y_1)=(2,2)$

So, the slope of the line is given by:

$m=\frac{y_1 -y_0}{x_1 -x_0}=\frac{2-(-2)}{2-1}=\frac{4}{1}=4$

And substituting into eq.(1), we find:

$y-(-2) = 4(x-1)$

Which rule describes a translation that is 8 units to the right and 2 units up?

Fofino [41]

(x-8, y+2).

When translating figures, a translation to the right subtracts from the x-coordinate (sort of the opposite of how we think of graphs that go to the right). Translations up would be adding to the y-coordinate.
