Write the equation of the line that goes through (-4,13) and (8,49).
algol [13]

Answer:

y=3x +25

Step-by-step explanation:

First calculate the slope:

m = (y1 - y2)/(x1-x2)

m = (49 - 13)/(8-(-4))

m= 36/12 = 3

so we have

y = 3x + b

subtitute a point:

49=3(8) + b

b=25

the equation is y=3x +25

Which ordered pair is a solution to the system of equations? Use any method to solve. 4x-y=5, x+y=10
fomenos

Answer:

The ordered pair ( 5, 15)  is a solution to the system of given equations.

Step-by-step explanation:

Consider the given equations,

4x-y=5 .......(1)

x+y=10  .......(2)

We have to find the ordered pair which is a solution to the system of given equations.

We solve the system by elimination method,

Adding both equation , to eliminate y ,

⇒ 4x - y +( x+y ) = 5+ 10

⇒ 4x - y + x + y = 15

⇒ 5x = 15

⇒ x = 5

Put x = 5 in equation (1) , and solve for y,

We get,

4x - y = 5 ⇒ 4(5) - y = 5 ⇒ y = 20 - 5 ⇒ y = 15

Thus, the ordered pair ( 5, 15)  is a solution to the system of given equations.
