Step-by-step explanation:
I hope this is right !
C, and D. They’re parallel so they’re never going to cross.
Answer:
the slope of MN= -5-1/3-(-6)=-2/3
two lines are parallel>> slopes are equal
equation of line = (y-y'=m(x-x'))
therefore, y-1= -2/3(x-6)
y-1 = -2/3x + 4
y+2/3x=5
Answer:
(10, - 9 )
Step-by-step explanation:
Given the 2 equations
y = - 2x + 11 → (1)
y = - 3x + 21 → (2)
Substitute y = - 2x + 11 into (2)
- 2x + 11 = - 3x + 21 ( add 3x to both sides )
x + 11 = 21 ( subtract 11 from both sides )
x = 10
Substitute x = 10 into either of the 2 equations and evaluate fir y
Substituting into (1)
y = - 2(10) + 11 = - 20 + 11 = - 9
solution is (10, - 9 )
