Answer:

Range: [-4, 2]

General Formulas and Concepts:

<u>Algebra I</u>

Range is the set of y-values that are outputted by function f(x).

Step-by-step explanation:

According to the graph, our y-values span from -4 to 2. Since both points are closed-dot, they are included in the range:

[-4, 2] or -4 ≤ y ≤ 2

Point A (6,2) is translated using the vector <-5,2>. Where is the new point located?

Dominik [7]

<h3>Answer: (1,4)</h3>

======================================================

Explanation:

The notation <-5,2> is the same as writing the translation rule $(x,y) \to (x-5,y+2)$

It says: move 5 units to the left and 2 units up

The point (6,2) moves to (1,2) when moving five units to the left. Then it ultimately arrives at (1, 4) after moving 2 units up. You could move 2 units up first and then 5 units to the left later on, and you'd still arrive at (1, 4). In this case, the order doesn't matter (some combinations of transformations this won't be the case and order will matter).

---------

Or you could write out the steps like so

$(x,y) \to (x-5, y+2)\\\\(6,2) \to (6-5, 2+2)\\\\(6,2) \to (1, 4)\\\\$

We see that (6,2) moves to (1, 4)

Find the equation of the line with slope m=1 that contains the point (1,2)

AnnyKZ [126]

Answer:

y = x + 1

Step-by-step explanation:

We can use the point-slope formula to write an equation for this problem. The point-slope formula states: <em>(y - y1) = m (x - x1) </em>

Where m is the slope and (x1 y1) is a point the line passes through.

Substituting the slope and the values from the point in the problem gives:

( y - 2 ) = 1 ( x - 1 )

We can also solve for y to put the equation in slope-intercept form. The slope-intercept form of a linear equation is: <em>y = mx + b</em>

y - 2 = 1x - 1

y = 1x - 1 + 2

<em>y = 1x + 1 or y = x + 1 </em> * are just the same.
