Answer 1

Answer:

1.) $slope=2$

2.) $slope=-3$

3.) $slope=\frac{1}{4}$

4.) $slope=-\frac{4}{5}$

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:

$(x_{1},y_{1})\\\\(x_{2},y_{2})\\\\\frac{y_{2}-y_{1}}{x_{2}-x_{1}}=slope$

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 $\frac{y}{x}$

• When you move up, the number will be positive $(\frac{+y}{x})$. If you move down, the number will be negative $(\frac{-y}{x})$.
• If you move to the right, the number will be positive $(\frac{y}{+x})$. If you move to the left, the number will be negative $(\frac{y}{-x})$.
