4x + 2y=4 and 3x -y= -7
Molodets [167]

Answer:

y =  4

x = -1

Step-by-step explanation:

4x + 2y = 4     Eq. 1

3x - y = -7       Eq. 2

from the  Eq. 2

3x = y - 7

3x + 7 = y        Eq. 3

Replacing the value of the Eq. 3 in the Eq. 1

4x + 2(3x+7) = 4

4x + (2*3x + 2*7) = 4

4x + (6x + 14) = 4

10x + 14 = 4

10x = 4 - 14

10x = - 10

x = -10/10

x = -1

from the Eq. 3

3x + 7 = y

3*-1 + 7 = y

-3 + 7 = y

4 = y

Check:

from the Eq. 1

4x + 2y = 4

4*-1 + 2*4 = 4

-4 + 8 = 4

Write the slope-intercept from of the equation of the line through the given point with the given slope through (-1,4), slope =
g100num [7]
The point-slope form is y - y1 = m(x - x1) where x1 ad y1 are the coordinates given and the m is the slope, which is given also. Plugging these in, we have
y - 4 = -2(x - (-1)), which simplifies to y - 4 = -2(x + 1)
