Solve the system by the elimination method. x + y - 6 = 0 x - y - 8 = 0

1 answer:

5 0

X+y=6 --> Equation 1
x-y=8 --> Equation 2
Equation 1 - Equation 2 =
2y =-2
y = -1

x+y = 6 --> Plug y value into equation
x + (-1) = 6
x-1 = 6
x = 7

y = -1, x = 7

Find the slope that passes through the two points. (9,3) and (6,7)

JulijaS [17]

Answer:

m=4/-3

Step-by-step explanation:

the equation for slope (m) when given two points is (y2-y1)/(x2-x1)

we are given the points (9,3) and (6,7)

we can label the points:

x1=9

y1=3

x2=6

y2=7

now substitute into the equation

m=(7-3)/(6-9)

subtract

m=4/-3

the slope is 4/-3

hope this helps!
