Answer:

Equation of the line that is parallel tox-3y = 9 and passes through the point  (3,-1) is

y+1= - \frac{1}{3} (x-2)

Step-by-step explanation:

Slope of line x-3y = 9 is -1/3

Since Parallel lines have same slope. Therefore slope of line passing through the point (3,-1) is also -1/3.

Equation of line in point slope form is given as

y-y_1=m(x-x_1) ---------- (1)

Here

m=-\frac{1}{3}  \ \  and \ \ (x_1, y_1)= (3, -1)

substituting values in equation (1)

y+1= - \frac{1}{3} (x-2)

Find the vertex, the axis of symmetry, and the y-intercept of the graph.
UNO [17]

<u>Given</u>:

Given that the graph of the parabola.

We need to determine the vertex, the axis of symmetry and the y - intercept of the graph.

<u>Vertex:</u>

The vertex of the parabola is the point at which the parabola changes its direction.

From the graph, it is obvious that the parabola changes its direction at the point (-2,0)

Hence, the vertex of the graph is (-2,0)

<u>Axis of symmetry:</u>

The axis of symmetry is the line that divides the parabola exactly into two equal halves.

Hence, from the graph, it is obvious the line x = -2 divides the graph exactly into two equal halves.

Hence, the axis of symmetry is x = -2.

<u>y - intercept:</u>

The y - intercept of the parabola is the value of y when x = 0.

In other words, the y - intercept of the graph is the value of y when the line passes through the y - axis.

Thus, from the graph it is obvious that when x = 0, the value of y is -3.

Hence, the y - intercept of the graph is -3.
