Answer:

1 41/56 or 97/56

Step-by-step explanation:

To add fractions, you must first find a common denominator. The easiest way to do this is to multiply the two denominators, 7 and 8. The product of these two numbers is 56, your new denominator. Then, you cross-multiply the numerators.

6/7 + 7/8

7*8 = 56 (denominator)

You multiplied 7 by 8, therefore you must also multiply the 6 by 8 to keep the fractions proportional. Use the same method to multiply 7 by 7.

48/56 + 49/56

Now that the denominators are the same, you can add the numerators.

97/56

If necessary, you can turn this improper fraction into a mixed number by dividing 97 by 56. The result is written before the fraction, and the remainder is written over 56.

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 $(\frac{y}{-x})$ .
