2x + 7y = 4.....multiply by 2
-4x - 3y = 14
------------------
4x + 14y = 8 (result of multiplying by 2)
-4x - 3y = 14
----------------add
11y = 22
y = 2
2x + 7y = 4
2x + 7(2) = 4
2x + 14 = 4
2x = 4 - 14
2x = - 10
x = -5
solution is : (-5,2)
Answer:
M is congruent to P, N is congruent to Q, and O is congruent to R.
Step-by-step explanation:
Congruent angles are angles with exactly the same measure.
Answer:
• From the general equation of a line:
- m is slope
- b is y-intercept.
→ Consider points (4, 4) and (2, 3)
→ find the y-intercept:
• Therefore, equation of a blue line is
