Answer:

The line is:

y = 1/2x + 4

The student correctly plotted one point:

(0,4)

Incorrectly plotted the second point. Instead of (2, 2) it should be:

y = 1/2*2 + 4 = 1 + 4 = 5
point (2, 5)

As a result the student got a negative slope and wrong line.

Correct one is attached

Answer:

The slope is $\frac{1}{2} x$ so the line would go up one over two instead of down one over two, therefore the graph would look like this:

Use the elimination method to solve this system.

leva [86]

Answer:

The solution for this system is: $x = -1, y = 1$

Step-by-step explanation:

The problem states that we have to solve this system by the elimination method

In the elimination method, we transform the system in such a way that one variable can cancel each other. With this, we find the result of the other variable. Then, we can replace the variable we found in any of the equations, and we have the value of the variable that we had initially canceled.

In this problem, we have the following system:

$1) -6x + 5y = 1$

$2) 6x + 4y = -10$

If we add equations 1) and 2), the variable x is going to be eliminated

$1) + 2)$

$-6x + 6x + 5y + 4y = 1 - 10$

$9y = -9$

$y = \frac{-9}{9}$

$y = -1$

Now, we can replace the value of y in any of the equations, to find x:

I will replace in equation 2)

$6x + 4y = -10$

$6x + 4(-1) = -10$

$6x = -6$

$x = \frac{-6}{6}$

$x = -1$

The solution for this system is: $x = -1, y = 1$

Determine the most precise name for quadrilateral ABCD. Answers: parallelogram quadrilateral rhombus kite angles: (7,6) (3,5) (2

devlian [24]

Answer:

rhombus

Step-by-step explanation:

It is helpful to plot the points on a graph. There, you can see that the rise and run of each segment are 1 and 4 (or vice versa). This tells you they are the same length, but not perpendicular.

A quadrilateral with all sides the same length, but not perpendicular, is a rhombus.
