How do you find the correct equation? Follow these steps.

First, plug 0 in for X and solve for Y . Does the y value match what is on the graph? 0 in this case?

a. 0 = -2(0) True - This could be an answer
b. 0 = 0 + 4 False - This cannot be an answer
c. 0 = 2(0) True - This could be an answer
d. 0 = 0 - 4 False - This cannot be an answer

Now we are down to 2 possible answers A and C. Now take another point on the line, say x=-2 and repeat, does the answer match what is on the graph? (4). 

a. 4 = -2(-2) True
c. 4 = 2(-2) False

As only A matches, A must be the answer. With graphing problems, when you have to find the correct equation, always choose X=0 as the first point (assuming it has a Y value) and eliminate answers. I hope this helps.

a figure that has a vertex at (2,3) has the y-axis as a line of symmetry. Tell the coordinates of another vertex of the figure
aleksley [76]

Answer:

-2, 3

Step-by-step explanation:

That would mean that the other side (the y axis splitting it) would be the same numbers but different signs. The figure's vertex (2,3) is from the 1 quadrant and the one across the y axis is (-2,3) which is in the second quadrant.

hope this helps!!

Hi there!

\large\boxed{\text{ UVY} = 65^o, \text{ VYZ }= 65^o}

We can begin by finding ∠VUY so we can solve for ∠UVY.

∠VUY is supplementary to ∠TUY, so:

180 = 144 + ∠VUY

∠VUY = 36°

In a triangle, angles sum up to 180°, so:

180 = 36° + 79° + m∠UVY

m∠UVY = 65°

Solve for m∠VYZ by comparing the angle to m∠UVY because the angles are alternating interior angles. Thus:

m∠UVY = m∠VYZ = 65°.

System of equations graphed below had How many equations?
Dominik [7]

Answer:

<h2>A. 0</h2>

Step-by-step explanation:

The solution of the system of equations are the coordinates of the point of intersection.

We have two parallel lines. The intersection point does not exist.

Therefore, this system of equations has no solution.
