3. Answer: y = 4
<u>Step-by-step explanation:</u>
Need to find the slope (m):
=
= 0
Now input ONE of the points (1, 4) and the slope (m = 0) into the Point-Slope formula:
y - y₁ = m(x - x₁)
y - 4 = 0(x - 1)
y - 4 = 0
y = 4

4. Answer:
<u>Step-by-step explanation:</u>
<h3>Answer:</h3>
infinite solutions
<h3>Step-by-step explanation:</h3>Add the two equations.
... (-4x) + (y) = (y +3) +(-4x -3)
Add 4x -y to both sides.
... -4x +y +4x -y = -4x +y +4x -y
... 0 = 0 . . . . . true for all values of x (or y)
Both equations describe the same line.
_____
The graph shows the first equation as a red line. The second equation is shown using a "blue dot" texture, so you can see it overlays the red line.
