Solve the system, or show that it has no solution. (If there is no solution, enter NO SOLUTION. If there are an infinite number
liberstina [14]

Answer:

The system has an infinite set of solutions (x,y) = (x, \frac{x-5}{4})

Step-by-step explanation:

From the first equation:

20x - 80y = 100

20x = 100 + 80y

x = \frac{100 + 80y}{20}

x = 5 + 4y

Replacing on the second equation:

-14x + 56y = -70

-14(5 + 4y) + 56y = -70

-70 - 56y + 56y = -70

0 = 0

This means that the system has an infinite number of solutions, considering:

x = 5 + 4y

4y = x - 5

y = \frac{x - 5}{4}

The system has an infinite set of solutions (x,y) = (x, \frac{x-5}{4})

1. Write an equation in point-slope form for the line through the given point with the given slope.
ElenaW [278]

Answer: y + 2 = \frac{-1}{2} ( x - 4 )

Step-by-step explanation:

The equation of a line in point - slope form is given as ;

y - y_{1} = m (x -  x_{1})

x_{1} = 4

y_{1} = -2

m = \frac{-1}{2}

Substitute the values into the equation , we have

y - (-2) = \frac{-1}{2}( x - 4 )

y + 2 = \frac{-1}{2} ( x - 4 )

Which could be written as :

y + 2 = y + 2 = \frac{-1}{2} x + 2
