X intercept (-10,0)
y intercept (0,-5)
Answer:
Vertex: (-2, 0)
Focus: (-2, 1/4)
Directrix: y = -1/(4a)
Step-by-step explanation:
Given that a parabola has a general form of:
The vertex is at:
The focus falls on the symmetry axis (x=h) of the parabola at:
The directrix is a straight line described by:
If we are given the parabola:
Then:
The vertex of the parabola is (-2, 0)
The focus of the parabola is (-2, 1/4)
The directrix of the parabola is given by the equation y = -1/(4a)
Answer:
y=3x+5
y=-2x-1
y=-4x
y=1/2x+2
Step-by-step explanation:
These are linear functions(y=mx+b). m stands for the slope and b stands for the y intercept. After plugging in your slope, you use the coordinates they give you to find the y intercept. To find the y intercept plug in the y coordinate into the y in y=mx+b, and plug in the x coordinate into the same equation.
