Use intercepts to graph the linear equation -2x+7y=-21 Question 2
Anna11 [10]

Answer:

The point representing the y-intercept is: (0, -3)

The black dot represents the y-intercept on the attached graph. It is very clear at y = 0, x = -3.

The point representing the x-intercept is: (10.5, 0)

The red dot represents the x-intercept on the attached graph. It is very clear at x = 0, y = 10.5

Step-by-step explanation:

Given the linear equation

-2x+7y=-21

Determining the y-intercept

We know that the value of y-intercept can be determined by setting x = 0, and determining the corresponding value of y.

substituting x = 0 in the equation

-2x+7y=-21

-2(0) + 7y = -21

0+7y = -21

7y = -21

divide both sides by 7

7y/7 = -21/7

y = -3

Therefore, the point representing the y-intercept is: (0, -3)

The black dot represents the y-intercept on the attached graph. It is very clear at y = 0, x = -3.

Determining the x-intercept

We know that the value of x-intercept can be determined by setting y = 0, and determining the corresponding value of x.

substituting y = 0 in the equation

-2x+7y=-21

-2x+7(0) = -21

-2x + 0 = -21

-2x = -21

divide both sides by -2

-2x / -2 = -21 / -2

x = 21/2

x = 10.5

Therefore, the point representing the x-intercept is: (10.5, 0)

The graph of the linear equation containing the y-intercept (0, -3) and x-intercept (10.5, 0) is shown and attached below.

The red dot represents the x-intercept on the attached graph. It is very clear at x = 0, y = 10.5

Please check the attached graph.

What is parallel to 3x-4=1
Licemer1 [7]

Answer:

<h2>x = a, where a is any real number</h2>

Step-by-step explanation:

3x-4=1\qquad\text{add 4 to both sides}\\\\3x-4+4=1+4\\\\3x=5\qquad\text{divide both sides by 3}\\\\\dfrac{3x}{3}=\dfrac{5}{3}\\\\x=\dfrac{5}{3}\to\text{it's a vertical line}\\\\\text{All vertical lines are parallel to the given line.}\\\\x=a\ \text{where}\ a-any\  real\ number
