The slope of the line l is the opposite reciprocal of y+2x=9. Rearranged the equation to y=9-2x and we get a slope of -2. The opposite reciprocal of -2 is 1/2.
y-y=m(x-x)
y-3=.5(x-4)
y=.5x+1
At the x-intercept, y=0, so
0=.5x+1
-1=.5x
x=-2
the system has no solution.
Option C is correct.
Step-by-step explanation:
We need to solve the system of equations by substitution
Putting value of x from eq(2) into eq(1)
As as 0≠4is not true, we cannot find the value of y so the system has no solution.
Option C is correct.

Answer:
b
Step-by-step explanation:
a: is not because in the distribution property, the answer would be for a, 9x+63.
b: yes.
c: it's subtracting, not adding. The question states adding
d: 7 is not the one being multiplied in the question, 9 is. Therefore b is right
The explaining is not good but im pretty sure it's b..
Answer:
Vertical Angles!
Step-by-step explanation:
Very simple!
Vertical angles are a pair of angles that are equal in degree measure.
Essentially, they are equal to each other. Nothing more to it.
This means that !
I presume you have done math before, so this solves to be:
(I don't have a degree sign, but it should be there in your answer.)
Hope this helps!
P.S. How's life?
