Answer:
2x + y = 5
y = 4x – 1
Substitute (2, 1) into system, then:
2x + y = 5 => 2 x 2 + 1 = 5 => 5 = 5 (satisfied)
y = 4x– 1 => 4 x 2 - 1 = 1 => -7 = 1 (not satisfied)
=> Option 3 is correct.
Hope this helps!

Is that everything for the problem??

Answer:
Step-by-step Explanation:
Extend the sides AD and BP. This creates 2 congruent triangles using ASA. Triangles CBP and adjacent triangle are also congruent bc of ASA. This makes 3 congruent triangles (transitivity). That means just finding the area of the constructed large triangle, you find the area of the parallelogram. Since point P is the midpoint of B_, P_ also equals 9. Using the formula for the area of a triangle, and Pythagorean theorem (9-12-15), 12*18/2=108, which is the area of the parallelogram.

Answer:
-4.5
Step-by-step explanation:
The y-intercept can be found by setting x=0 and solving for y.
-2y = 9
y = -9/2 = -4.5 . . . the y-intercept
__
As an ordered pair, this is (0, -4.5).
48-32=16
so yur answer is 16
hope it helped
