Answer:

y = -5

Step-by-step explanation:

-3x +9y = -57

Let x = 4

-3*4 +9y = -57

-12 +9y = -57

Add 12 to each side

-12+12 +9y = -57+12

9y = -45

Divide each side by 9

9y/9 = -45/9

y = -5

What is the slope of the line?​
yulyashka [42]

Answer:

3

Step-by-step explanation:

In simple terms, the slope of the line is \frac{Rise}{Run}

The equation states that the slope is how much the graph, rises goes up, divided by how much it goes across, to the right.

This graph goes up 3 units and goes to the right by 1 unit. Use the lattice points, the marked points, to make the decisions. You can pick any two points, and you will see that when simplified, it will equal 3.

This is because the graph is proportional.
