Answer:

y = 2x - 5

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = 2x + 3 ← is in slope- intercept form

with slope m = 2

Parallel lines have equal slopes, so

y = 2x + c ← is the partial equation of the line

To find c substitute (3, 1) into the partial equation

1 = 6 + c ⇒ c = 1 - 6 = - 5

y = 2x - 5 ← equation of parallel line

If point U is reflected across the x = -3, what are the coordinates of its reflection image?
Elena L [17]

The coordinates of U after the reflection are: (-5, -3)

<h3>How to get the coordinates after the reflection?</h3>

By looking at the graph, we can see that the coordinates of point U are:

U = (-1, -3)

And we want to reflect it across the line x = -3.

Notice that because this is a vertical line, the y-component does not change by the reflection. Only changes the x-component, such that the distance between the original coordinates and the final coordinates to the line don't change.

The original x-component is x = -1, the distance to the line is:

d = |-3 - (-1)| = 2 units.

Then the new x-component will also be at 2 units of the line, but in the other direction:

new x-component: x = -3 - 2 = -5

The coordinates of U after the reflection are:

(-5, -3)

Answer:

x = 12, y = 1

Step-by-step explanation:

y - x = -13

-4x + 3y = -51

Find y.

y = -13 + x

Plug y into 2nd equation

-4x + 3y = -51

-4x + 3(-13 + x) = -51

-4x + -39 + 3x = -51

-x = -12

x = 12

y = -13 + 12

y = -1
