Match each system of equations to its graph. y = 2x + 1 y = x + 2 y = 3x y = x + 3 y = 2x − 2 y = x − 2 y = 2x + 3 y = x + 5 y =
GalinKa [24]

The matchup are:

  • (1st picture): y=2x+3 and y=x+5
  • (2nd picture): y=4x+2 and y =3x+2
  • (3rd picture): y=2x+1 and y =x+2
  • (4th picture): 3x and x+3

<h3>What does the graph of an equation shows?</h3>

The graph of the linear equation is known to be one that often brings or  set the  points that can be found on the coordinate plane and it is one that shows all the solutions to the equation.

Note that when  all variables stands for real numbers, a person can be able to use graph to show the equation and this is often done through plotting the points to show a pattern and then link up the points to have all the points.

From the above, the pictures that have all the points as shown on the graph are:

  • (1st picture): y=2x+3 and y=x+5
  • (2nd picture): y=4x+2 and y =3x+2
  • (3rd picture): y=2x+1 and y =x+2
  • (4th picture): 3x and x+3

Write an equation of the line that passes through (9, 2) and is parallel to the line below
Alex777 [14]

Answer:

y=5/3x-13

Step-by-step explanation:

We must use the point-slope form(parallel lines have the same slope, remember that!)

y-y1=m(x-x1)

y-2=5/3(x-9)

y-2=5/3x-15

y=5/3x-13

lesya692 [45]

Answer:

5,418.2 feet

Step-by-step explanation:

Nadia is carrying out mountain climbing.

She started climbing the mountain at an altitude of 19.26 feet below the sea level.

Nadia changed her altitude by climbing a total of 5,437.8 feet from her starting position.

Therefore, Nadia's altitude at the end of her climb can be calculated as follows

= 5,437.8-19.6

= 5,418.2

Hence Maria's altitude at the end of her climb is 5,418.2 feet
