Answer:

x = 3

y = -5

Step-by-step explanation:

5x+2y= 5 equation 1

3х - у = 14 equation 2

using equation 2 we have:

3x - 14 = y equation 3

using equation 3 in equation 1 we have:

5x + 2(3x -14) = 5

5x + 6x -28 = 5

11x = 5+28

11x = 33

x =33/11

x = 3

using equation 3 we have:

3(3) - 14 = y

y =9-14

y = -5

A line includes the points (10, -10) and (1,8). What is its equation in slope-intercept form?

Anettt [7]

Answer:

y=-2x+10

Step-by-step explanation:

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

m=(8-(-10))/(1-10)

m=(8+10)/-9

m=18/-9

m=-2

------------------

y-y1=m(x-x1)

y-(-10)=-2(x-10)

y+10=-2x+20

y=-2x+20-10

y=-2x+10
