Answer:

y = (6/5) - (7/5) x

Step-by-step explanation:

goal: to rearrange the equation such that it takes the form:

y = f(x) ; where f(x) is an expression in terms of x

Given:

7x+5y=6 subtract 7x from both sides

5y = 6 - 7x (divide both sides by 5)

y = (6-7x) / 5

y = (6/5) - (7/5) x

Write an ordered pair for each point graphed below.

Viefleur [7K]

Answer:

$\boxed{(-1,4)}$

Step-by-step explanation:

The point is located in Quadrant II of the graph, where x-values are negative and y-values are positive.

Each marking on the graph represents one unit of distance. The two <em>axes</em> meet at the origin, where the coordinate point is equal to $(0,0)$ .

So, you can count backwards once from the origin to get your x-value ⇒ $-1$ and count up upwards four times from $x=-1$ to get your y-value ⇒ $4$ .

Finally, place these in a coordinate point $(x,y)$ ⇒ $\boxed{(-1,4)}$ .
