The vertex is the highest point on a downward-opening parabola or the lowest point on an upward-opening parabola.
Answer:
3x-5y=-15
Step-by-step explanation:
The slope form equation is: y=mx+b so once you plug in the numbers available through the diagram you get.
y=3x+4
Answer:
x = 5 y =-2
Step-by-step explanation:
You can substitute the 4y in,
7x - (-3-x) = 43
7x + 3 + x = 43
8x + 3 = 43
8x = 40
x = 5
Then plug the x back into the equation,
4y = -3 - 5
4y = -8
y = -2
