The ordered pair (8,5) represents a point on the graph of a proportional relationship. Which ordered pair also represents a poin

makkiz [27]

Given the ordered pair:

(8, 5)

Let's find the ordered pair that represents a point on the same graph assuming this is a graph of a proportional relationship.

Here, we have:

(x, y) ==> (8, 5)

Since this is a graph of a proportional relationship, let's find the constant of proportionality.

We have:

$K=\frac{y}{x}=\frac{5}{8}$

This means when x is 1, y is 5/8.

Thus, the ordered pair that also represents a point on the same graph is:

$(1,\frac{5}{8})$

ANSWER:

$\text{ B. (1, }\frac{5}{8})$

Find an equation for the line that passes through the points (-5,-5) and (1,4)

Andreas93 [3]

The general line through (a,b) and (c,d) is

(c-a)(y-b)=(d-b)(x-a)

Here that's

(1 - - 5)(y - - 5) = (4 - -5)(x - - 5)

6(y+5)=9(x+5)

6y + 30 = 9x + 45

-15 = 9x - 6y

3x - 2y = -5

Answer: 3x - 2y = -5

We could put that in slope intercept form,

2y = 3x + 5

y = (3/2) x + 5/2

Answer: y = (3/2) x + 5/2
