Answer:
A. Subtraction
B. Subtraction
C. x+4=11
-4 -4
D. x=7
Step-by-step explanation:
Answer:
1+1 = 2
Step-by-step explanation:
-1 + 3 = 2
y = 3x - 1
x - y = -9
Subs y in second equation.
x - (3x - 1) = -9
x - 3x + 1 = -9
-2x = -9 - 1
-2x = -10
x = -10/-2
x = 5
Subs x
y = 3x - 1
y = 3.5 - 1
y = 15 - 1
y = 14
The slope of a line that passes through (3,4) and (5,8) is 2
