The answer, is CD. The 3rd one
Answer:
No solution
Explanation:
the problem 2x+y=2 can be written into slope intercept form by subtracting 2x from both sides. You should now have y= —2x + 2 following the formula y=mx+b. The formulas y= —2x - 1 and y= —2x + 2 now have the same slope but different y-intercepts so the answer CANT be infinitely many. In order to have a single (one) solution, you’d need a similar y- intercept. This being said, you would eliminate “one solution”
Keep in mind:
* Y intercept is b in the formula y=mx+b *
It would be 1080
Just use a calculator
(-1,2)(2,-1)
slope = (-1 - 2) / (2 - (-1) = -3/3 = -1
y = mx + b
slope(m) = -1
use either of ur points...(-1,2)...x = -1 and y = 2
sub and find b, the y int
2 = -1(-1) + b
2 = 1 + b
2 - 1 = b
1 = b
so ur equation is : y = -x + 1 <==
