Step-by-step explanation:
The unit rate is also known as slope. Slope is the change in the y values over the change in the x values:
However, with certain graphs, the slope can be found in a simpler manner.
- You start at one point and move across the y-axis, then move along the x-axis until you reach another point on the same line.
- Make sure you move on the y-axis first, then the x-axis. Record the slope as spaces moved in each
- When you move up, the number will be positive . If you move down, the number will be negative .
- If you move to the right, the number will be positive . If you move to the left, the number will be negative .
The focus is left of the vertex, so the parabola opens to the left. The vertex is halfway between the focus and directrix, so the directrix is the vertical line
x = 2
