Find the equation of the line with slope = 2 and passing through (-3 , 4)
coldgirl [10]

Answer:

y = 2x + 10

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 )

Here m = 2. thus

y = 2x + c ← is the partial equation

To find c substitute (- 3, 4) into the partial equation

4 = - 6 + c ⇒ c = 4 + 6 = 10

y = 2x + 10 ← equation of line

Neporo4naja [7]

Answer:

The system of equations is

x+y=15

19x+8y=164

Step-by-step explanation:

Let

x------> the number of videos of new releases

y-----> the number of classics videos

we know that

x+y=15 ------> equation A

19x+8y=164 ------> equation B

Using a graphing tool

Solve the system of equations

Remember that the solution of the system of equations is the intersection point both graphs

The intersection point is (4,11)

see the attached figure

therefore

the number of videos of new releases is 4

the number of classics videos is 11
